The negative and positive pulses are given to the trigger and threshold pins of 555 through the light activated phototransistors t1 and t2.
Remote control lamp circuit.
We used a simple remote and tsop 1738 ir receiver at the transmitter and receiver side of the circuit.
Remote controlled light switch is an application where a remote is used to turn on or off an ac light.
We have used ic 4017 to convert it into a push on push off switch.

The collector of t2 is connected to the trigger pin 2 through diode d1.
Normally we use remote controls to turn on or off appliances like tv dvd player music.
In this remote controlled switch circuit we are using tv remote to on off the ac light by pressing any button of remote and using the tsop1738 at receiver end.
