Attiny85 and 84 Projects and Tutorials

A collection of projects for the Attiny mincontrollers. The Attinys can be programmed with the Arduino IDE, and a lot of Arduino projects can be made to work on an Attiny with minor alterations.

The Attiny 85 is an 8 pin IC with 5 pins available for Digital I/O, 3 analog inputs, and 2 PWM pins.

The Attiny84 is a 14 pin IC, it has all eight pins on the PA registers available for digital output, digital input, analog input, and three of them are good for PWM output, in addition the PB7 pin also supports PWM.
