Need help with circuits and photocell

[sanddrag]

There are ways to do this without a microcontroller, but it honestly is probably easier to use one. Quick question: does the "x" number of times have to be a very accurate and consistent number?

You may look into using something like a PICAXE 08M2 or 14M2 microcontroller to read a CdS (LDR), and some transistors to drive the motor.

This isn't too difficult really.

Also, does it have to be THAT motor, or can it be a continuous rotation servo? If the latter, this is a piece o cake.
