How to use 12V Relay module with Arduino to control High Voltage Devices | How Relay Module works
In this video, I have shown how to use 12V Relay module with Arduino to control High Voltage AC Devices like 220v bulb, motor etc with Arduino code and arduino relay circuit diagram. I have also explained how the relay module works with the circuit diagram.
You can download the Gerber file for the PCB and order it from

I would like to thank you Seeed Studio Fusion PCB service for sending me the prototype PCB for this 4 channel 12 volt relay module.
Required components list for this Arduino relay control circuit:
1. 12 v relay 4no [K1 K2 K3 K4]
2. 1K ohm 0.25-watt resistor 5no [R1 R2 R3 R4 R9]
3. 220 ohm 0.25-watt resistor 5no [R5 R6 R7 R8]
5. Diode (1N4007) 4no
6. LED 5mm 1.5V 5no
7. BC547 NPN Transistors [T1 T2 T3 T4]
8. 220-ohm 0.25-watt resistor 1no [R4]
9 AC Connector
10 Arduino UNO
Please check all the required electronics components before soldering on PCB.
