The key to the simulation is the Arduino code that controls the relays. You can write a simple program that allows serial commands to control each relay. For a basic example where sending '1' turns relay 1 on and '0' turns it off, you can use the digitalWrite() function. More sophisticated programs can allow for two-digit commands, where the first digit selects the relay (0-3) and the second sets its state (1=ON, 0=OFF). The control program is compiled in the Arduino IDE to generate a .HEX file, which is then loaded onto the Arduino model in Proteus to drive the simulation.

Each relay features three screw terminals: Normally Open (NO), Common (COM), and Normally Closed (NC).

: The circuit is closed by default and opens when triggered. Simulation Steps in Proteus
