[Phillip Torrone], has written a piece over at Make entitled “Why the Arduino won ... We can show them just how simple of a circuit they could use to blink their LEDs. We could show them ...

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 ...

The end result is you can have the circuit simulator on the left of the screen and a Web-based Arduino IDE on the right side. But how does it work beyond the simple demo? We wanted to find out.
