As you can see in the system diagram the brains of Magpi Radio is a Raspberry Pi computer. These are small, cheap linux computers that pack a lot of horse power, making them perfect for internet-of-thingsy projects like this. Here are some of the benefits of the Pi when picking your hardware:
• Speed: The Pi runs at 700 mhz with 512 MB of RAM. I never experienced any latency when making this project.
• Audio: Playing audio files is a breeze through the audio jack and supports pretty much any format you throw at it.
• Programming: You’re not limited to a specific library or language. I wrote the Magpi software in Ruby to leverage the excellent Twitter gems (twitter and tweetstream).
You’ll also notice an Arduino in the diagram, which handled the physical interface (the knobs and light). The reason I used the Arduino in addition to the Pi is because the Pi doesn’t have great support for analog io. I was able to read the volume potentiometer with an ADC chip through the GPIO pins, but because there’s only 1 PWM pin I wasn’t able to control the RBG LED. (If you’re interested in using the Pi’s GPIO pins for sensor io, I’d recommend the WiringPi lib).
MCP3008 – 8-Channel 10-Bit ADC With SPI Interface – Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It’s super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great accompaniment to the Raspberry Pi computer, because its fun to have analog inputs but the Pi does not have an ADC.

In this guide I’ll show you how I built a simple WiFi sensor datalogger and optimized it to run for days on batteries. You can learn some useful power saving tips to apply to your own Arduino project!
Roughly every quarter my employer, Red Gate, has a ‘Down Tools Week’ which is a week long opportunity to hack on ideas that never get space in a normal work day. This cycle our theme is the Internet of Things, so I’m pulling together kits to get people up and running.
Earlier this week, Google bought Nest, a connected devices company, for $3.2 billion. This might seem like an ungodly sum for a company that makes thermostats and smoke detectors, but it makes absolute sense. Nest’s products are beautifully designed, their team is overflowing with talent, and they were the first company to figure out what the “Internet of Things” means to consumers and deliver products that people actually want.
But in order to do this, Nest had to spend millions of dollars on R&D to build the basic infrastructure behind the product. The high cost made it impossible for anyone but the extremely well-capitalized to enter the market and create connected things.
Well, we want to change that. At Spark, we’re making it easier to bring connected devices to market with the Spark Core, our Wi-Fi development kit, and the Spark Cloud, our cloud service for connected devices. And to prove it, we built our own approximation of the Nest Learning Thermostat in one day — and we’ve open sourced everything. In this process, we’ve come to respect the incredible technical challenges that Nest has solved while also coming to understand how much the game has changed since they first started.
What’s better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8×8 matrix or a 4-digit 7-segment display. Matrices like these are ‘multiplexed’ – so to control 64 LEDs you need 16 pins. That’s a lot of pins, and there aredriver chips like the MAX7219 that can control a matrix for you but there’s a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all, wouldn’t it be awesome if you could control a matrix without tons of wiring? That’s where these adorable LED matrix backpacks come in. We have them in two flavors - a mini 8×8 and a 4-digit 0.56″ 7-segment. They work perfectly with the matrices we stock in the Adafruit shop and make adding a bright little display trivial.
We count on WiFi and Bluetooth in our homes, but we don’t have appliances that provide self-description or reliable two-way communication. As a result, the Internet of Things for consumers is, in practice, a Basket of Remotes.
IoT isn’t just a fancy buzzword that describes how your refrigerator can let you know when you need to replace your spoiling milk or your rotting vegetables (although it can), it is so much more. How much more is only left to your imagination and to your budget. You can do as little or as much with IoT as you want. For example, if you operate food distribution business, you could install sensors in your trucks that send temperature, humidity, and dock-to-dock travel times back to your home office for analysis. You can also more accurately track the exact expense required to deliver each food product or container to the customer.
The Internet of Things is not just about gathering of data but also about the analysis and use of data.
In this guide, we are going to give a modern touch to gardening and connect some informations about your garden to the Internet. We are going to use a soil moisture & temperature sensor connected to an Arduino and a WiFi chip to automatically send measurements from your garden to the cloud.
We’ll use a service call Carriots to handle the data and display it nicely on a webpage. Then, an email or SMS alert can be send to you automatically if the moisture falls below a given threshold. The picture below represents the system when fully assembled and with the sensor buried into the soil next to a plant.
Don’t worry, you don’t actually need to have a garden or even plants (although we think plants are great to have) to use the content of this article: what you are going to learn can be used for any remote measurement projects. Let’s dive into the project!
Decorating a holiday tree with a strip of NeoPixel addressable RGB LEDs is a great way to get into the holiday spirit. Don’t settle for a simple fixed color or animation of the LEDs though, expose control of the lights through a web page to control them from a phone, tablet, or computer. You can even let your friends and family control the lights for maximum holiday entertainment!
This project will show you how to use an Arduino Yun or a CC3000 WiFi chip & regular Arduino to control a strip of NeoPixels through a web page. This project is a good example of interacting with an Arduino through a web page that you can use in your own Arduino projects.
Happy Manufacturing Monday! Just used the rockin’ Adafruit Perm Proto Board, Terminal Blocks and Photocell combined with an Arduino & Twine to have a CNC Milling Machine send a text message when it needs a tool change: thought you guys might enjoy the DIY video!
When we, PinMeTo, moved in to our office at MINC in the beginning of September we only had three keys to four persons and an extra key cost 500 sek so i built an automatic door lock for the door. Maybe cheaper to just buy an extra key but not as fun.
Electric Imp: What is the electric imp? In essence, the Imp provides an easy, integrated way to connect almost any hardware device both to other devices and to internet services. It’s more than just a WiFi card, or even a WiFi module with processing built in – it’s an integrated platform that deals with the drudgery of connectivity, allowing you to concentrate on the application instead of the mechanics. The Imp itself is very small – 32mm x 24mm x 2.1mm – but packs a lot inside. (read more)
Is checking and filling your pet food dish a constant daily chore? Have you ever wished you could be notified on your phone when the dish is empty? With this project you’ll learn how to build a pet food dish that does exactly that by sending an SMS text message when the dish is empty! This is way better than giving your pet a smartphone: our cat MOSFET ran up a huge texting bill and then refused to pay it.
This project is a great example of using an Arduino, CC3000 Wi-Fi module, and the Amazon Simple Notification Service to send notifications such as text messages. You can even use the knowledge and code from this project to add notification capabilities to your own Arduino projects!
Have you ever wished you could know when something you put in the oven was done cooking? Maybe not 10 minute cookies but how about the 3 or 4 hour turkey roast? You might have used a gadget like a kitchen probe thermometer to monitor the temperature of food in the oven. Probe thermometers are great at measuring the temperature of cooking food, however there are a couple ways they can be improved. First, most probe thermometers (the inexpensive ones at least) can’t be monitored remotely, so you need to be in the kitchen constantly watching them. Second, these thermometers only display the current temperature and don’t give any prediction of when the food will be at a desired temperature.
This guide will show you how to build a thermometer that solves both the problems above. By using an Arduinoand Adafruit CC3000 WiFi breakout, you can build a probe thermometer that logs temperature data to Amazon’s DynamoDB cloud database service. With the temperature data in the cloud, you can monitor it remotely over the web, and even use the history of measurements to predict when the food will be ready!
