As for one of my new robot features (Farfalle, the walking robot), I wanted Farfalle to turn on when it is light out, using a photoresistor. The only problem is that I cant find a schematic that I am looking for. I was going to use a LM339 (quad Comp) or a LM324 (quad OPAMP). The output of the transistor would control the base of a PNP transistor, which would switch on the power supply to the 7805. For more details on Farfalle, go to the Farfalle:coming soon! thread under robotics chat. Also, it must be able to be ajustable using a potientiometer. Thanks!
