Yes I used just a bare AVR chip but the arduino nano is easier to use and I've seen them for $3 with free Shipping. They can hold at least 2000 lines of code and run at 16 MHz. The Mano has more then enough PWM and ADC Pins and can drive an lcd display for status and control. You get quite a lot of computer for $3
