Updated Electrical and Code Flow Chart, hooray! April 23, 2006

Now that we have both components of the stepper motor driver, I updated the electrical diagram using the spec sheets for the new IC's. Basically, the driver moves the motor one step for each pulse it receives. It can take pulse signals in the kHz range, meaning that the stepper could (theoretically) move at a couple thousand rpms. Should work for what we need it for. We also need a zenner diode, but these are fairly common so I think we can just find one in the shop.

Also uploaded is the program flow chart describing the workings of the code, before any stepper motor nonsense is added.
