Bits moving atoms

I've hooked up my microcontroller, driver & motor. It's alive...

What are we looking at?

In the foreground (bottom left) is the motor with a marked CD attached. It spins back and fowards. Yippee!
At the top center is a DMM measuring frequency. The generated signal is 20kHz, which the meter mostly shows (it gets a little confused with all the changes).
At the top right is a CRO showing the voltage at the motor. Here you can see the PWM signal increasing in duty cycle and reversing polarity.

All for simple back and forth motion. A rubber band could have provided that...
Next will be fitting the optical encoder to the motor. This will provide feedback on the actual motor position. After that we should be able to accurately move the motor.
