Twelve PWM outputs from an ATtiny85

This project describes how to get 12 analogue PWM outputs from an ATtiny85, so you can drive 12 LEDs with individual control over each LED's brightness. David Johnson-Davies writes: Each LED can be set to a brightness between 0 (off) and 63 (fully on). The demonstration program shows a...
