It combines an Arduino-compatible processor with a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer.

At first glance, you may think such a powerful mosfet is superfluous here, but the selection is intentional. Note that when the Arduino is powered it starts working as per the code, but the RGB LED ...

Here’s a no-PCB Arduino that doesn’t obscure the DIP footprint of the AVR chip. It’s built on an ATmega88 chip, and includes a programming header, reset button, a couple of filter… ...

Here’s a handy hack for an Android controlled, Arduino driven, RGB light setup. [Kerimil] recently wrote up this project on the Arduino.cc, and is sharing all of the source code and plans. Wh… ...
