Video capture project - rotating camera using stepper motor

Hi sbright33, very interesting work you did there but i'm having a bit of trouble to follow the code + where can i see the schematics of the circuit (preferably a picture of how it actually looks instead of schematics)?

How can I use your work to accomplish my needs of controlling the rotation speed of the motor to spin y degrees in x minutes, cutting off the power between steps to cool down?

Thanks!
