	~~Look into using shift registers for IO.~~		After motor
			* Drive Stepper
	== Stepper ==		* Drive DC with rotary encoder
	~~First, control it~~ with ~~manual switches.~~		* Driver Servo motor

	~~I'd like to build a driver around the AtTiny2313 or an AtMega8. Use 4 pins for the driver out, and 1 pin out to indicate if the~~ motor is stopped. One input pin for direction and one for start/stop. The rest will be used for speed and steps. The idea is that another controller can give the driver and order like "take 120 steps over 3 seconds".

	~~I should also do this at least once with a real stepper driver.~~
