--- 4 Channel Relay Module Library For Proteus -

Once you have downloaded the library files (usually 4RELAY.LIB and 4RELAY.IDX ), follow these steps:

void setup() // Configure all relay pins as outputs for(int i = 0; i < 4; i++) pinMode(RelayPins[i], OUTPUT); --- 4 Channel Relay Module Library For Proteus

To see the theory in action, consider a real-world example. The "Arduino 4 Channel Relay using ATmega328P with Proteus Simulation" is a project designed to demonstrate how a standard Arduino board can safely switch four 12V relays using a ULN2003 driver IC. Once you have downloaded the library files (usually 4RELAY

Connects to the common terminal only when the relay is activated. To see the theory in action
