By this circuit you can turn ON and OFF an electric appliance up to 10A by any IR remote control such as remote control of TV, satellite, air conditioner ... etc.
Red LED run when the load is turn OFF, it help you to find the switch position in dark.
I put here two circuits, they are similar but the first contain a transformerless power supply circuit to convert 220v to 12v and 5v for running the 12v relay and the IC, but the second circuit is easier to make because used a 5v mobile charger to running the circuits by 220v.
Parts list:
IC 4017
IC 7805
Transistor 2N2222
Transistor S9012
Diode 1N4007
Bridge diode 1A
Zener diode 12v 1w
LED
IR receiver 1838A
Capaciror 470nF 400v
Capacitor 220uF 16v
Capacitor 0.47uF
Resistor 270 ohm 2w
Resistor 1K
Resistor 100K
Resistor 47 ohm
Resistor 220 ohm
Relay 12v
