Switching of Coil Relay Modules
Switching of Coil Relay Modules Just Arduino Things | TW TechieTube Try to switch on and off a Coil Relay using Arduino UNO in various methods. Principle: The function of the relay coil is to create a magnetic field that actuates the switch mechanism of the relay. The coil is energized by an electric signal from a power source. When the coil is energized, it attracts the contact and completes the circuit within the relay, turning on or off the load being controlled. The relay coil is an electromagnet that can be operated by a small electric current to control a larger electric current. Components Required: Arduino UNO (1) 1 Channel 5vDC Relay Module (1) ...
