--- 4 Channel Relay Module Library For Proteus Extra Quality

The 4-channel module in Proteus mimics the physical 4-Channel 5V Relay Board , typically featuring:

Connect the terminal of the relay to one terminal of your Lamp .

Connect Arduino Digital Pins to Relay Module input pins IN1, IN2, IN3, and IN4 respectively. Load Side (High Voltage) --- 4 Channel Relay Module Library For Proteus

Before writing any microcontroller firmware, connect a LOGICSTATE device to the IN1 through IN4 pins.

void loop() if (Serial.available() >= 2) Input[0] = Serial.read(); // Read first digit (relay number) Input[1] = Serial.read(); // Read second digit (state) int relayNum = Input[0] - '0'; // Convert ASCII to integer (0-3) int relayState = Input[1] - '0'; // Convert ASCII to integer (0 or 1) The 4-channel module in Proteus mimics the physical

Navigate to your Proteus 8 Professional (or your version) installation folder. The default path is often:

Amplifiers that provide enough current to energize the internal relay coils. void loop() if (Serial

) and search for "Relay Module" or the specific name from the downloaded library. to the ground. Connect the control pins ( ) to your microcontroller (like an Arduino Uno). : These modules are often active-low , meaning a "Low" signal from your code triggers the relay. Interactive Simulation

Connect the of your AC Alternator to the Common (COM) terminal of the relay.
