Remote controlled appliance switch circuit

Description. Here is a versatile remote controlled appliance switch that can ON or OFF any appliance connected to it using a TV remote.  IR remote sensor IC TSOP 1738 is used for recieving the signal. Normally when no signal is falling on IC3 the output of it will be high.This makes Q1 OFF.When a signal
