Step 1: Components Needed:
IR Transmitter Circuit:
* IR LED
* IC 555
* 9VDC battery with connector
* Capacitors 100uF, 0.01uF, 1nF
* Resistors 1K, 20K, 470
* Push Button
IR Receiver Circuit:
* Capacitor 1uF
* Resistors 1K, 10K, 100K
* Transistors BC547, BC557
* Diode 1N4007
* 6Volts DC Relay
* 9V DC Battery with connector
Step 2: Making the Remote:
Make the Remote circuit and connect it with the 9 volt battery
Step 3: Testing Our Remote:
I've already made a transmitter circuit with connected with an LED. So I've tested it with that.
Step 4: Making the Receiver Circuit:
Make the circuit as detailed in the circuit above.
Step 5: Connect It With Relay and Bulb
Connect the 6V Relay with the circuit. And connect a bulb with the relay and 220V AC power supply.
Step 6: Now It's Ready:
Now our remote and transmitter circuits are ready. Switch on the Remote and see the bulb glowing. Press the button again to switch the bulb off.
