Description
In this project, we will make a **3-Channel Arduino Relay Shield Circuit** for relay based applications. In this circuit, we have designed an isolated PCB for 3 relays. By using this **Arduino Relay Shield**, we can operate 3 AC appliances at a time. We have put a two pin screw terminal blocks (Neutral, NO) for connecting appliances. Here we have provided PCB layout, circuit diagram, and Gerber files so that you can build or directly order this Relay Driver Module.
