4 Channel Relay Module Library For Proteus New

// Define control pins for the 4-channel relay module const int relayPins[4] = 2, 3, 4, 5; void setup() // Initialize all four pins as outputs for(int i = 0; i < 4; i++) pinMode(relayPins[i], OUTPUT); digitalWrite(relayPins[i], HIGH); // Keep relays OFF initially (Active-Low configuration) void loop() // Cycle through each relay channel sequentially for(int i = 0; i < 4; i++) digitalWrite(relayPins[i], LOW); // Turn relay ON delay(1000); // Wait 1 second digitalWrite(relayPins[i], HIGH); // Turn relay OFF delay(1000); // Wait 1 second Use code with caution. Troubleshooting Common Simulation Errors

A functional 4-channel relay module library for Proteus has been successfully designed and validated. The component accurately replicates the electrical behavior of a physical module, including input logic, coil activation, and contact switching. Engineers can now simulate complete microcontroller-to-load control systems without cluttering schematics with discrete components. The library is ready for use in educational projects, home automation simulations, and industrial control prototyping. 4 channel relay module library for proteus new
