Booty Box.

Uses an Adafruit Wave Shield! Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. It’s low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.

The PAN management box outside and inside

From the Adafruit Foru, uberhund writes:

The PANdora Box can send one of 16 messages selected by the brass knob connected to a rotary encoder in the center of the base section. The smoky plex allows the various parts within to be seen, aided by an LED strip light of variable color and intensity, and mirrors on the interior walls. Wacky button sounds are played by the Wav shield as the user rotates the brass knob through each message. Pressing the brass knob instructs an Arduino to send the selected Wav file name across the PAN to the remote listeners which then find and play the Wav file, with, or sometimes without, a preamble. The preamble can be selected from a list appropriate to the message, such as creaky doors, or impersonations. The message itself is usually something useful (but not always) like Kids, please take out the garbage.

PRIZES: $600 GRAND PRIZE, SIX $60 PRIZES (ADAFRUIT STORE)

Inspired by Dug the dog from Pixar’s “Up.” Made using Arduino Pro, Adafruit Wave Shield and Hall effect sensors, electronic surplus and craft store detritus.

An early Arduino project by PaintYourDragon.

Interactive Iron Man repulsor by Advancer Technologies on Instructables. More than just wearable…it’s triggered by the electrical activity of your forearm muscles! How cool is that? The Adafruit Wave Shield for Arduino also features prominently.

Simply flex your forearm muscle and hear the repulsor charge up, then relax your forearm to fire (lighting up the LEDs on your palm and playing explosion sound effects). As an added flair for realism, when you turn on the system, J.A.R.V.I.S.’s voice takes you through the boot up and calibration sequence.

Sound Effects Suit Jacket by Kenneth Guglielmino:

Inspired by sitcoms and cartoons. I thought it would be fun to be able to add sound effects to my own life. So I made a sound effects suit jacket. The sound samples are triggered by a control panel with 4 buttons (3 for samples, 1 for changing sound banks). And then being played from an Arduino + Wave Shield through a portable speaker. All the hardware is kept within the inner jacket pockets while in use.

8-bit Annoying Person Remover via Hackaday:

Still trying to solidify that reputation as the office Grinch? This project will let everyone know you’re a complete jerk in no time. It’s called the 8-bit Annoying Person Remover. It detects when someone enters your office at which point it starts to play the Super Mario Bros. theme song while the display counts down 400 seconds. Just like in the game the music gets faster at the end and when it stops they know it’s time to get the heck out.

The hardware inside isn’t too complicated. An Arduino and a Wave shield do most of the work. The song played is stored on an SD card and can easily be changed. There’s a speaker mounted under the top heat vent of the enclosure. The device defaults to displaying the time of day, but monitors a motion sensor on one side to detect when someone comes through the door. This also works when someone leaves, cutting off the music and resetting the display.

Check out this neat 8-bit Annoying Person Remover project.  It uses an old NES as the shell or enclosure of the project, and a whole bunch of Adafruit components. It basically senses when a person has entered your office, plays some cool Nintendo music, and starts a countdown timer.  That person has just a few minutes to say what they need to say before the timer goes off.

Get the code and parts list here.

The project above uses the Adafruit Music & Sound Add-on Pack for Arduino. It’s a Wave shield party pack! Just add an Arduino to create your own iPod-killer, audio art, sound-effects box!

I built my first project with an arduino and the wave shield from adafruit (I had a halloween themed wedding, so I wanted to rig up a “talking skeleton” using the parallax range finder and wave shield).

Check out this excellent audio doorbell project created by Adafruit community member Jarruda — with a little help from the Adafruit forums!

So when I bought my house, I noticed it had probably the most boring doorbell on the planet. Then I saw the Adafruit’s Wave Shield and saw inspiration. This is my first actually completed hobby electronics project, so I’m pretty proud of it, even if it’s really simple.

Main Parts:

• Pre-R3 Arduino Uno
• Wave Shield 1.1
• Velleman 3 Watt Mono Amplifier # K 8066

Power for the doorbell comes from a 16V transformer off mains power (120V). It’s run through a 50V 4A bridge diode rectifier into an electrolytic cap and a ceramic cap to smooth the pulsed DC, then two diodes to drop the voltage by ~3V before powering the mono amplifier and being split off for the UNO’s Vin.

The doorbell is connected like any other button, sending 5V out to the doorbell and in to a digital pin configured as an interrupt. Using a pullup resistor and pulling the pin to ground wasn’t used to lower the demand on the linear regulator running on voltage that’s a bit higher than I’d like. To further reduce power usage, the atmega328 is put into PWR_DOWN sleep in between doorbell rings.

Also, thanks to adafruit_support for providing help!

My next project is a little more ambitious, a thermostat that can use a wireless sensor for temperature readings.

Richard Clarkson made this lovely night light/speaker/hanging cloud and writes:

On one hand ‘Cloud’ is an Arduino controlled, motion triggered lightning & thunder performance. On the other it is a music activated visualizer & suspended speaker unit. The cloud is made by felting hypoallergenic fiberfill to a sponge casing which forms the frame of the cloud and holds the speakers and componentry. The felting tool used is a custom made felting tool made from the left over sponge and 4 felting needles. To control the functions of the cloud there are three tactile switches scattered around the base. The concept references real clouds which constantly change shape through the switches requiring constant exploration to find the right switch to turn the right feature on or off.

Richard used a Wave Shield, PIR motion sensor, yellow LEDs, white EL wire, and a few tactile on/off switches for this project. He even made his own yellow audio cable to look more like lightening connected to the bottom of the cloud.

Mike writes in:

I was hoping to show this off on Show & Tell but it did not come to pass. As you had asked about projects using Adafruit products, I had built a Cylon Pumpkin with a twist – using a Wave Shield and infrared remote to trigger sounds and turn on or mute the eye sound.

I had originally had a problem with the Wave Shield not working but your eagle-eye support forum moderator spotted a potential cold joint (even where I thought I’d touched them up). My thanks to the support. I decided after the build that I needed a better soldering iron so I ordered a Hakko from you and will put it to good use.

Thanks for the great customer support, creativity in what you stock, and the Adafruit Learning Center helping to show the potential of your products.

Over in the Adafruit forums, Tim shared with us his huge 8ft tall Minecraft Creeper project that him and some friends built.  It is controlled by an Arduino, and the sound effects come from an Adafruit Wave Shield.

In Minecraft there are a variety of monsters, the most troublesome of these is the “Creeper.” Creepers are plant monsters who explodes when they get next to you usually leaving a crater in the aftermath. Woe to the player who is surprised by their distinctive SSSSSSSSSSSSSSSSBOOOM!

In respect to Minecraft’s king of monsters I and some of my cohorts thought it would be entertaining to undertake a project to build a creeper prop with some animated features for Holloween this year. Our hope is to give an authentic creeper experience to some trick-or-treaters! Naturally, making robocreeper actually explode is not something we can really do in our urban environment, but we can load the thing with RGB LEDs, motors, motion sensors, and a loud speaker that will let you know when you have entered the blast zone!

Be sure to check out the build log gallery on Google+. Nice work Tim!

Have you ever done something silly on a lark and then found it was a big hit? So it went with a “beta test” Halloween idea on the Adafruit Show & Tell last week of my electronic demon costume. This video is a summary of what was done there… and what I’m now scrambling to finish properly before the big day! Video on YouTube (please subscribe!) and Vimeo.

The code for the LED mask with voice is in the adavoice repository on Github. This references the Wave Shield Voice Changer and Multiple LED Backpack tutorials.

Some updates since this was shot: a Ustream chat participant during Show & Tell suggested using a paintball mask as a base. I’m currently working on the faux ribcage idea… there may be enough space to move most of the electronics there and have just batteries in the pack. We shall see!

“Star Mario” Halloween costume.

With a bit of hacking a $1 plastic pumpkin is upgraded: a sensor embedded in the nose detects when people get close and will play scarey sounds and animates LEDs on the face.

My absolute favorite costume.  The robot costume that responds when treats are added.

Another amazing Mario costume.

Learn to make a speaking, card-reading toy! The Babel Fish helps you learn to say words and phrases on RFID flash cards by reading the card and playing an associated sound file loaded on an SD card inside. This project is very straightforward and could make a great jumping-off point for your own awesome RFID and Wave Shield project! Video on YouTube (subscribe to our channel!) and Vimeo. Head over to the Adafruit Learning System for the complete guide.

Check out this new piece of hardware on Kickstarter, the Hauntbox.

The Hauntbox makes physical things happen based on inputs from sensors in the real world. Adding automation to your haunts and other projects is now incredibly simple.

The Hauntbox is a prop controller and automation machine that is browser-configured, open source and Arduino-compatible. It’s cool because you can automate inputs and outputs with no programming!

The creators of the Hauntbox were on our weekly Show and Tell!  Check out the video below. If the video below doesn’t work, click here to start watching at 8:34, when they start talking about the Hauntbox.  They are even selling a custom sound module that is based on Ladyada’s Wave Shield design.

Adafruit customer Philippe Chrétien built a quiz buzzer system for his mother.

Last Christmas I built a Quiz Buzzer System for my mother. She is a big fan of television quizzes and love to organize some with her friends and family. The particularity of this project is that you can choose your team buzzer sound from a list of more than 30 digital sounds.

The system is composed of a main console, 8 buttons, a power supply and a set of telephone cables. The core of the console, built in a plastic project box, is made of an Arduino Duemilanueve micro-controller coupled with an Adafruit wave shield. The 8 buttons are made out of small project boxes and arcade buttons, again from Adafruit. The buttons are connected to the main console using telephone jack and cables.

Really well packaged and put together system.  I really like how each team gets to choose their buzzer sound before the game.  Uses our Arduino Wave Shield and Arcade buttons!

The GPS Dot and its Discontents @ Inside GNSS.

What is the predictable endpoint of the trend toward ever cheaper, ever smaller, and ever more sensitive GPS receivers? It’s the GPS dot: a miniature GPS tracking device that we’ll buy in bulk and stick on almost everything of value that we own. But the dot has a dark side: the capability it enables for secret and potentially malicious tracking of others. The need to protect ourselves from invasive tracking will motivate use of subversive tools such as GPS jammers and spoofers. A rise in the use of these illicit tools has the potential to wreak havoc on the «good» GPS receivers — those built into our critical systems and infrastructure. The result: A looming showdown between privacy and GPS integrity. 

Old phone restored with an Adafruit Waveshield! via HaD. Simon writes -

I’ve been playing with Arduinos for a wee while now. These are small microprocessors you can build things with. They use the idea of shields which are small daughter boards that connect to the Arduino to provide extra hardware to do useful things with. One shield I have been playing with the the Adafruit Waveshield. This little board allows you to hook an SD card up to the Arduino and play .wav files from it. These are in mono, 22kHz format. Not HiFi but good enough for little projects. I decided to use one in my old phone to make it play music.

This is about the phone in my old Austin 7 garage where I am building an Austin 7 special. I don’t actually like phones (horrible, nasty things) so this one never actually did anything useful. I used an Arduino and a Adafruit Waveshield to make it into a musical phone playing suitably period songs.

My most recent completed project is this Robot donation box that is being placed at the entrance of a Pittsburgh non-profit art gallery. Make sure you check out the video of it in action at the bottom of the page. It’s using a wave shield attached to a Modern Device BBB (a separate BBB is driving the lights and motion in his head). Code help was generously given in the help forums here. These shields are great.

David Lee Roth scream box – Arduino & Adafruit WaveShield!.

I finished this today. It’s a box with a button. When you push the button, it plays a random David Lee Roth scream. Arduino based, with adafruit’s wav shield. Runs on a 9v battery. The red button on the upper right is the power button, the knob on the upper left is volume. The speaker is in the bottom of the case.

Contact-free jukebox. Dominik writes -

I built this RFID enabled jukebox with an Adafruit Waveshield for our daughter, Anna. I drew animals representing the audio tracks on RFID cards. Anna can pick an animal that she likes, wave it in the front of the jukebox and the song is being played.

Arduino Plays Connect4. Scott writes -

I’ve used your kits on a few of the projects described on my blog.  I just posted one that shows the Wave Shield being used by an Arduino-powered Connect4 player.  I made the Connect4 board by CNC — I’d love to write it up so others could make it but I think a traditional circuit board would be easier for others to work with.  Any suggestions on making an oversized board like that inexpensively?  Thanks.

Great Arduino + Adafruit WaveShield project!

Super Punch: Posters you can listen to. Jonathan writes -

A band set up cool listening stations around London. Around 30 seconds into the video, looks like they used Adafruit Wave Shields! 

I came across what I think is the awesome end results.

Winfred, who is a Windows Systems Administrator, shows us a project for adding sound to a motorcycle using the Adafruit Wave Shield.

On a beautiful day I was thinking, wouldn’t it be cool if other devices also had start-up and shutdown tunes, just like your computer? For example, your TV, your car or your motorcycle? Since I was looking for a simple project to that uses an Arduino microcontroller, I decided to add the Windows XP Startup and Shutdown sounds to my BMW F650.

I love to see people having fun with projects like this!

Richard Davis made this “singing” ukelele using the Adafruit WaveShield. I really dig how it sounds thru the Small Stone phaser. Nice work, Richard!

I was in a need of an analog output output for my Arduino, and I found quite many different digital-to-analog converter (DAC) solutions by googling around. So finally I decided to gather them on one page as a reminder for myself and a guide for others. So here it comes!

As mentioned, if you need to add some sound to your next project the Wave Shield can be picked up at the Adafruit Industries store.

digitalmisery created this neat “jacob’s ladder” using EL wire and a WaveShield:

Created using LyTec electroluminescent (EL) wire, driven by a
IFW 3294 inverter (Coolight.com), with the Sparkfun.com EL Sequencer, an Arduino USB Board (arduino.cc), a WaveShield (adafruit.com) and a PIR Sensor.

A new take on an old favorite.

Cooper Bills and Anish Borkar, two EE students at Cornell, have created The Handy Lab Buddy, a multifunction device, based around an ATMega 644, that measures voltages, logic levels and frequencies, and then “speaks” the results via a wavetable. They write:

The Handy Lab Buddy is a tool every ECE should have. The four features of this tool include a talking voltmeter, logic probe, voltage averager, and frequency measurer. As a cheap and accurate device that outputs whatever being measured through speakers, it’s one of its kind and an essential tool for lab work.

The “voltage averager” feature is particularly interesting. It takes multiple voltage samples, and then outputs the average, as well as the min and max levels, over the speaker.

If you want to do this project yourself, they provide the schematic and code on the website. Alternatively, you could try something similar with an Arduino and a WaveShield.

Great job, guys!

Nice! waverp – An Arduino Library for recording and playing wave files on the Adafruit Wave Shield.

WaveRP is an Arduino library for recording and playing Wave files with the Adafruit Wave Shield. It records 8-bit mono files at 4,000 to 44,100 samples per second. Use of the Wave record/play library, WaveRP, requires the following: Arduino with a 5 volt 328 processor. Low noise power source such as a nine volt DC adapter or battery. Adafruit Wave Shield (version 1.1 is best but 1.0 works) Microphone preamp. A circuit for a simple preamp is included in the documentation. Microphone, PC type with 3.5 mm plug. See the documentation for details. SD/SDHC formatted with 32KB allocation units.

The Wave Shield!
Adding quality audio to an electronic project is surprisingly difficult. Here is a shield for Arduinos that solves this problem. It can play up to 22KHz, 12bit uncompressed audio files of any length. It’s low cost, available as an easy-to-make kit. It has an onboard DAC, filter and op-amp for high quality output. Audio files are read off of an SD/MMC card, which are available at nearly any store. Volume can be controlled with the onboard thumbwheel potentiometer.

This shield is a kit, and comes with all parts you need to build it. Arduino, SD card, tools, speaker and headphones are not included. It is fairly easy to construct andanyone with a successful soldering project under their belt should be able to build it.

The shield comes with an Arduino library for easy use; simply drag uncompressed wave files onto the SD card and plug it in. Then use the library to play audio when buttons are pressed, or when a sensor goes off, or when serial data is received, etc. Audio is played asynchronously as an interrupt, so the Arduino can perform tasks while the audio is playing.

• Can play any uncompressed 22KHz, 16bit, mono Wave (.wav) files of any size. While it isnt CD quality, it is certainly good enough to play music, have spoken word, or audio effects. Check out the demo video/audio at the webpage
• Output is mono, into L and R channels, standard 3.5mm headphone jack and a connection for a speaker that is switched on when the headphones are unplugged
• Files are read off of a FAT16-formatted SD/MMC card
• Included library and examples makes playing audio easy
• Please note that the library rather bulky, requiring 10K of flash and more than 1/2 K of RAM for buffering audio. It works fine using an ATmega168-based Arduino (or compatible) but for more complex projects I strongly recommend upgrading to an ATmega328!

More information, including design notes, schematics, library, examples, etc is at the Wave Shield webpage

• Latest Wave shield kit, works with more SD cards and with older NG Arduinos! Unassembled
• 2 GB SD card (brand may change, but we test one of each kind to verify it works well)
• Speaker – 3″ diameter (77mm), 8 ohm impedence, good response between 200Hz to 10KHz (10KHz is the max frequency the Wave shield can make). The speaker is rated for 1W so if you want you can even stick a small amp between the shield and the speaker to boost up the volume
• Some wire for connecting up the speaker

I’ve got the MeggySynth synchronized with an Arduino Waveshield, which has been preloaded with some slices of the Amen break. The MeggySynth is communicating via serial port with the Waveshield, and is triggering samples to be played on the Waveshield. The pattern is stored on the Meggy itself, since the Waveshield is sorely lacking in free ROM/RAM. Synchronization is still a little wonky. But I kind of like the stuttering sound. Other samples (like simple kicks and snares) sound better, but less interesting.

Foofers (the Dragon?) makes scaley costumes and has designed a “rar-box” based on a Arduino + Wave shield to play special effects. When the button-pad is pressed, different sounds are played through a speaker fitted into the mask. A bit late for his halloween, but a good idea for any costume that could use some extra-yiffy-spiffyness. Check out video and details on his livejournal

The ’328 has 32K of flash, and 2K of SRAM. Basically its got the capacity of an ATmega32 but in a slimmer package. These chips are notable for their ability to drop-in replace the ATmega168. So that means if you have an Arduino or compatible clone, it is a easy 2 minute swap.

If you have an Adafruit wave shield or GPS/datalogging shield, and you’re annoyed that the FAT16 libraries eats up so much flash and RAM, upgrading will definitely fix the problem.

I’ve merged my previous updates to the Arduino bootloader to the most recent release and also fixed 2 annoying bugs that have prevailed this long. (1. the missing signature bytes when using the bootloader directly and 2. the broken EEPROM code). Download the ’328-compatible bootloader files here.

There are 250 preprogrammed chips are in the Adafruit webshop or you can get blank chips from Mouser (but be warned that they’re backordered till mid-December)
