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...

ATtiny85 20MHz Internal Clock

Here is a new tutorial from technoblogy.com on how to run ATtiny85 with internal 20MHz clock. The ATtiny85 is rated at a maximum clock speed of 20MHz at 4.5 – 5.5V. For some applications it would be nice to get the maximum speed without needing to buy a 20MHz crystal, or tie up two...
