July 24th, 2008 RGB LED Controlled By An ATTtiny2313
The controller is actually just an ATTiny2313, running of it’s internal RC oscillator at 8MHz, soldered onto an universal board with a few resistors and wires. There are no control items - no buttons, no nothing. It just does what it does - makes the effect of LEDs randomly fading in and out using 9 channels of PWM. Unfortunately, the processor has only a few hardware PWM channels, so some of the channels had to be done by software.
