Kit 79A. LDR LIGHT/DARK ACTIVATED RELAY SWITCH

Kit 79A. LDR LIGHT/DARK ACTIVATED RELAY SWITCH. We wanted to do a light/dark switch as a kit. But we found. there were several types of basic circuit

LM741 Light Dark Sensor Circuit - Electronics

Build a light/dark sensing circuit to automatically turn on/off lights and other devices.

Circuit - 12v Light/Dark Lamp Switch - Circuits designed by David

At night, this circuit will route current to a 12v lamp, turning it on.

Circuit - 12v Light/Dark Switch - Circuits designed by David

The circuit below was designed for a 12v DC system. But, it could be modified for other voltage as well. It uses an inexpensive phototransistor as the light
