Hi Friends, in this video I will show you how to make a simple AUTOMATIC LIGHT On/Off Circuit using LDR and Relay. This device turns lights on automatically when it's night, and off when it is daytime. It is a sensor light switch. The circuit of the switch works on light sense.
You Need: 1. MOSFET 2N7000 2.LDR 3. 470k Resistor 4. 12V Relay 5. 12V Power Source
