A relay is a programmable electrical switch, which can be controlled by Arduino or any micro-controller. It is used to programmatically control on/off the devices, which use the high voltage and/or high current. It is a bridge between Arduino and high voltage devices. WARNING. See more Relay has two groups of pins: low voltage group and high voltage group. 1. Pins in the low voltage group are connected to Arduino, including three pins: 2. Pins in the high voltage group are … See more The relay can work with two modes: normally open mode and normally closedmode. These modes are the opposite. The “normally” means “if IN pin is connected to LOW (0V)”. See more Arduino controls a high voltage device by controlling a relay. Controlling a relay is simple. We just need: 1. Connect an Arduino's pin to the IN pin of the relay 2.
