- Relay

Relays are circuit elements that you can switch very high voltage and current values with simple signals (for example, a digital signal that you will produce with Arduino). When HIGH is sent to the signal pin of the relay, it will close the circuit and allow current to flow, and when it is LOW, it will open the circuit and close the flow. The maximum voltage it can switch is 250V and the highest current is limited to 5 A.
