In this video I'm demonstrating how to program and use Atmel ATtiny85 with Arduino code. If you have a small Arduino project and need only few input and output pins, you can substitute the 28-pin Atmega8/168/328 microcontroller with the small, 8-pin ATtiny85 chip. You'll save some space, simplify your project and decrease power consumption.
The ATtiny85 microcontroller offers digital, analog and Pulse Width Modulation pins.
By default Arduino IDE doesn't support the ATtiny chips, but High-Low Tech Group at MIT Media Lab created their own libraries and shared them publicly. You can download them free of charge here:
github.com/damellis/attiny/archive/master.zip

This tutorial is based on High-Low Tech Group's explanations found on their website:
