For the Arduino fanatics is this video already everything they need to know but for a novice or beginner, this needs more explanation, but still easy to make after that.

The ATtiny13 is the smallest and cheapest Atmel AVR 8-bit microcontrollers and it's loaded with sophisticated peripherals such as two 8-bit PWM channels and 4 channels 10-bit ADC.
