This is using two LEDs to sense the sun and send +- or -+ logic signals to a full bridge motor driver like L298 or [http:/www.redrok.com LED3X schematic]. I bought his. I recommend it.

I changed the front end logic to 4060 and 4011 ICs here, for fun. You could use this circuit to turn on an irrigation motor for a very short time every several hours (just omit the sun sensor and select appropriate timing pins and much lower oscillation frequency for the 4060).
