WebMar 4, 2024 · With the way a relay controls working circuit, you can close or open the working circuit by sending high or low level to the corresponding pins. Here, we connect the lamp to the port that is normally closed. When relay’s pin has high level, the relay closes the circuit and the lamp is on. 1. Reference program WebDFRobot Relay Shield V2.1 is a completely new design which is capable of controlling 4 relays at a time. The max switching power DC 90W or AC 360VA gives direct control by Arduino/DFRduino controllers through digital I/Os with external 9V supply.
