Switch Circuit With Infra Red
This circuit ease you to control any appliance with infra red remote. Can be used for electrical devices like lamp, fan, etc. With power supply from itself, the circuit make the application compact and easy to control. The circuit looks for any modulated IR source and uses it to control a TRIAC, which then switches any appliance connected to it’s socket. Its based on flip-flop switching.
