V Pin Relay Wiring Diagram
V Pin Relay Wiring Diagram. The polarity of the voltage does not matter. Warning: do not touch any wires that are connected to mains voltage.
Although there are various relay designs, the ones most commonly. In the above wiring diagram we have kept the jumper in place, due to which the electromagnet of the relay will be driven directly from the Arduino. Arduino GND pin - Relay module GND pin.
Arduino GND pin - Relay module GND pin.
Identify the hot power wire (red wire in the diagram above) in the cord leading to the light bulb and make a cut.
A wide variety of relay wiring diagram options are available to you, such as application, type. The polarity of the voltage does not matter. Place the relay's rated coil voltage on these terminals.
