A single channel relay board is sufficient.
Remote control lamp circuit diagram.
The negative and positive pulses are given to the trigger and threshold pins of 555 through the light activated phototransistors t1 and t2.
Circuit design of remote controlled light switch.
T1 t2 l14f1 2n5777.
Receiver circuit is connected to ac appliance via relay so that we can control the light remotely.
Alternatively the relay circuit can be built as per the circuit diagram.
The circuit works by pressing any key on the remote it can also operated manually by pressing switch s1 to on state.
A simple ir led with 38 khz pulse can be used as a remote control.
Similarly the emitter of t2 is connected to the threshold pin 6.
Remote controlled on off switch circuit.
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.
A 4 channel relay module is used in this project in order to control the light.
