Renewable Energy Monitor

Modified to roll the motor back and forth slightly slower.

This was a geared, 12v, 100rpm motor.

Power consumption issues apart, how would we modify this to act according to the logic of the CMOS controller described at: Automatic Chicken Coop Door?

We need:

1. To a pin reading 0/1 for the light level
2. Two pins each reading 0/1 for the upper and lower door switches
3. Logic that drives the motor forwards or backwards respectively when a 0 + 0 or a 1 + 1 condition exists
4. We could make the motor drives into functions to keep our code clean
