Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

This module is modeled after an Etch A Sketch and combines Arduino and Processing sketches. With the help of Processing, you can trace a line using two controllers (potentiometers). One of the knobs ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
