Make: Getting Started with Adafruit Trinket - PDF

Arduino-compatible - at a lower cost and smaller size - and low-power, the Trinket lets you make inexpensive and powerful programmable electronic projects. Getting Started with Adafruit Trinket gets you up and running quickly with this board, and gives you some great projects to inspire your own creations.

 Arduino's ubiquity and simplicity has led to a gigantic surge in the use of microcontrollers to build programmable electronics projects. Despite the low cost of Arduino, you're still committing about $30 worth of hardware every time you build a project that has an Arduino inside. This is where Adafruit's Trinket comes in.  

 This get-started guide provides the ability to focus on the concept and gives you the information to go from idea to project quickly and painlessly.
