--- 4 Channel Relay Module Library For Proteus

Double-click the relay module in Proteus. Verify that its voltage rating matches your digital control logic (e.g., set to 5V, not 12V).

void loop() // Relay 1 ON, others OFF digitalWrite(2, HIGH); digitalWrite(3, LOW); digitalWrite(4, LOW); digitalWrite(5, LOW); delay(2000); --- 4 Channel Relay Module Library For Proteus

Wire pins to digital output pins on your Arduino (e.g., Pins 2, 3, 4, and 5). 3. Wiring the Load Side (High Voltage) Double-click the relay module in Proteus

A relay is an electrically operated switch. It uses a small, low-power signal from a microcontroller to control a much larger electrical load, effectively acting as a bridge between the logic world and the real world. Modern relay modules often include , which provides electrical separation, protecting your delicate microcontroller from potentially damaging voltage spikes. Modern relay modules often include , which provides

Export the compiled binary ( .hex file) from your Arduino IDE. Double-click the Arduino UNO component inside Proteus, click the folder icon next to the "Program File" field, select your .hex file, and click OK.

Displays the visual on/off state of each individual relay channel.
