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.<br /><br />You Need:<br />1. MOSFET 2N7000<br />2.LDR<br />3. 470k Resistor<br />4. 12V Relay<br />5. 12V Power Source<br />
