The Solarbotics Arduino Freeduino Enclosure (SAFE) is a laser-cut acrylic case for your Arduino Mega. It also has the added feature that it can house an Arduino or Freeduino instead with a MEGA amount of space left inside.
The larger 3 watt RGB LEDs are very bright and colorful, but if you don't get the power just right - POOF! Now your RGB is R(nothin')B. The Star Controller tames this LED so you can power it up with 5 to 12V and use any regular 5V signal to control each channel.
This book will guide you through building and programming 30 Arduino projects, with detailed instructions and lists of required parts, introduce you to C programming and the scientific principles behind the projects.
