The Thing Posted January 21, 2006 Posted January 21, 2006 I want to create a circuit that dims or brightens a LED. I want the LED to glow BRIGHTLY as the environment around it gets darker, and vice versa. I know I have to use a photovoltaic cell and maybe transistors, but the exact wiring of this circuit escapes me. I will probably also use a separate power source for the LED, but maybe not. Help please!
5614 Posted January 21, 2006 Posted January 21, 2006 Wire an LED and an LDR (light dependant resistor) as a potential divider. Potential dividers are quite simple - look em up on google if you need to.
The Thing Posted January 21, 2006 Author Posted January 21, 2006 ... OMG OMG Thanks 5614. Arrrg I need to go shoot myself. EDIT: Crap, missed.
