If you have an E-Paper Display form Adafruit, this library will allow you to draw points, lines, circles, ellipses, ASCII text and Unicode text. Oh, and display images (in the WyoLum Image Format). Please consider this an alpha release and help us find the bugs.
NEW PRODUCT – BlinkStick – Smart USB-Controlled LED Pixel Kit – This mini kit is an easy way to add a single RGB-color LED to your computer. After assembly (requires a soldering iron, solder and diagonal cutter – not included) plug it into you Mac, Windows or Linux computer’s USB port and run the open source software to control the bright LED’s color. No drivers required!
While there are a few USB-pixel controllers out there, we like this one for its comprehensive software & examples for popular operating systems. There’s also some code written that allows use of the blinkstick through a web-browser, using BlinkStick.com as an event-provider!
This pack contains all parts required to build one BlinkStick. It’s designed to be small (the size of an average USB Flash key), but still easy to solder even for beginners. The kit comes with a preprogrammed ATTiny85 chip with the latest BlinkStick firmware.

Finally got some spare time to put this together and I got it to work like a charm. Got the sample code to run 64 LEDs. So Stoked! Now I just need to figure out how to address the LEDs with the Esploras varied sensors.
Thanks for the help, and for providing such neat things to tinker with!
NEW PRODUCT – PIXEL Guts Kit – Bluetooth Controlled 32×32 RGB LED Matrix Kit (new video!). Control a 32×32 LED matrix with your Android device or PC over Bluetooth, no soldering or coding required! This is a 32×32 (1024 total) LED RGB matrix connected to a custom IOIO Mint so that custom graphics can be sent from any Android device to the display. Originally designed for a kickstarter, now the ‘guts’ of the PIXEL project are available for pixelated graphics fans who want to create their own custom enclosure.
Comes with dozens of fun animations. Or easily create and add your own. Comes with a 32×32 LED Matrix, IOIO Mint with custom ‘shield’, 5V 4A power adapter (US plug but can take 100-240VAC input), a Bluetooth module for the IOIO and a Bluetooth module for your PC (in case it doesn’t have one), and necessary cabling. Android tablet/phone not included. You’ll need to have your own Android device for controlling the PIXEL kit.
This guide walks through the process of assembling and configuring our LCD displays with USB/serial backpack and stand as a realtime system monitor. These displays are great for monitoring the health and status of “headless” systems such as servers, small Raspberry Pi installations, or as an auxiliary information display on your regular computer. You can get one of our cute acrylic stands in the Adafruit shop.
NEW PRODUCT – Acrylic Stand for 16×2 Character LCD. Here is a mini-kit to get your 16×2 LCD standing up straight on your table. Made of 3mm black acrylic pieces, with 4 x 1″ nylon screws & 4 x nylon hex nuts, it goes together in a jiffy and looks super-spiffy!
Designed specifically for our 16×2 USB/Serial backpacks, but will work with nearly any 16×2 character LCD setup.
NTSC/PAL (Television) TFT Display – 2.0″ Diagonal – Yes, this is an adorable miniature television! The visible display measures only 2.0″ diagonal, the TFT comes with a NTSC/PAL driver board. The display is very easy to use – simply connect 6-15VDC to the red and black wires, then connect a composite video source to the yellow and black wire. Voila, a television display! There’s a little button to adjust the LED backlight brightness (5 levels) – there is no other adjustment available but we found that the color and contrast look great right out of the box.
To demonstrate it, we took some photos with the display connected to a Raspberry Pi, but it will also work connected to any analog composite-video output such as a YBox or Propeller w/Video out. It will not work with a device that only outputs VGA, HDMI or any other digital video signal.
Please note, these miniature displays are very delicate and require care to avoid ripping the delicate flex connector. These are best used by electronics geeks who have experience and are comfortable working with delicate electronic components. WE CANNOT REPLACE DAMAGED DISPLAYS if you are not careful and rip the flex connector! (read more)

What’s a wearable project without LEDs? Our favorite part of the Flora platform is these tiny smart pixels. Designed specifically for wearables, these updated Flora NeoPixels have ultra-cool technology: these ultra-bright LEDs have a constant-current driver cooked right into the LED package! The pixels are chainable – so you only need 1 pin/wire to control as many LEDs as you like. They’re easy to sew, and the chainable design means no crossed threads.
Our goal from early on was to create something cute and actually engaging to play with that we could eventually give back to the Adafruit community. We seized on the idea of an RGB color picker, the “Koloric Konfabulator” and then featured “Ladyada’s E is for Electronics” — Adafruit awesome Creative Commons coloring book — as the material for participants to color. Check out our video showing how it works!

This tutorial is for our 1.8″ diagonal TFT display. It comes packaged as a breakout or as an Arduino shield. Both styles have a microSD interface for storing files and images. These are both great ways to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it requires little memory and only a few pins. This makes it ideal for use with small microcontrollers.
The shield version plugs directly into an Arduino with no wiring required. The breakout version can be used with every kind of microcontroller.
Every Wednesday is Wearable Wednesday here at Adafruit!

Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!
NEW PRODUCTS – rePaper – 1.44″ and 2.7″ Graphic eInk Development Boards – Ever since the Kindle eReader came out, we’ve been wanting a nice small graphical eInk display that is easy to use with a microcontroller. And finally our desires have been fulfilled with the rePaper 1.44″ and 2.7″ development boards from Pervasive Displays! We’re excited to offer these very interesting display breakouts for hackers who want to start playing with small eInk displays.
These kits come with a driver board that is powered from 3V and has level shifting on all the I/O pins so it can be used with 5V microcontrollers such as the Arduino. The PCB also has a lot of driver circuitry required to keep the display running smoothly such a temperature sensor, FLASH memory and ZIF socket. All signals are broken out to a 20 male socket header on the left. A 20 pin socket/socket cable is included to make wiring easier and there’s also some extra-long header so you can plug these wires into Arduino header or a breadboard.
The displays are 2.7″ diagonal with 264 x 176 resolution and 1.44″ diagonal and 128 x 96 resolution, true eInk graphical display. These are intended for use as small dynamic signage in grocery stores since a barcode displayed on it can be scanned by a laser barcode-reader. The displays do not require any power to keep the image and will stay ‘on’ without any power connection for many days before slowly fading. Of course, they’re also daylight readable and are very high contrast. This makes them excellent for data-logging applications, outdoor displays, or any other ultra-low power usages.
The good news is that rePaper/PDI have provided a suite of example code for Arduino UNO/Leonardo as well as the MSP430 Launchpad and also have a site with some documentation on how to wire up the displays and datasheets. However, please note: the displays are quite large pixel-wise and to dynamically write to the display requires 3K of RAM – more than the Arduino Uno or Leo/Launchpad so for those boards, the example code only displays what is stored in a 8-pin FLASH chip in the devboard. (By default that FLASH contains a picture of a cat and some imaged text, see photos above).
