Hall-effect spinner circuit
First draft of a circuit for connecting a CD-ROM motor to an Arduino so that it acts as a rotary sensor. I want to make it into a spinner control, rather like those which are used to control video playback. Normally, the Hall-effect sensors are connected to the motor driver chip and control the commutation. I've wired them to a comparator chip (TLC3704) and then to the Arduino.
