Module Library For Proteus //top\\ - --- 4 Channel Relay

// Define Relay Control Pins const int relay1 = 2; const int relay2 = 3; const int relay3 = 4; const int relay4 = 5; void setup() // Initialize digital pins as outputs pinMode(relay1, OUTPUT); pinMode(relay2, OUTPUT); pinMode(relay3, OUTPUT); pinMode(relay4, OUTPUT); void loop() // Sequentially turn each relay ON (Assuming Low-Level Trigger Module) digitalWrite(relay1, LOW); delay(1000); digitalWrite(relay2, LOW); delay(1000); digitalWrite(relay3, LOW); delay(1000); digitalWrite(relay4, LOW); delay(1000); // Sequentially turn each relay OFF digitalWrite(relay1, HIGH); delay(1000); digitalWrite(relay2, HIGH); delay(1000); digitalWrite(relay3, HIGH); delay(1000); digitalWrite(relay4, HIGH); delay(1000); Use code with caution. 4. Running the Simulation

If the lamps turn on when the code dictates they should be off, your module operates on Active-High logic instead of Active-Low. Invert your code logic ( HIGH to turn on, LOW to turn off) to fix this.

Each channel breaks out into three distinct connections: --- 4 Channel Relay Module Library For Proteus

Copy the downloaded .LIB and .IDX files (e.g., 4ChannelRelay.LIB , 4ChannelRelay.IDX ) into the folder mentioned above. 4. Restart Proteus

Understanding the pins is crucial for proper simulation. A typical 4-channel module in Proteus will look like a small PCB with connection points. // Define Relay Control Pins const int relay1

Provides visual confirmation of the active channel. Why You Need a Specific Proteus Library

To use a in Proteus, you typically need to download external library files ( Invert your code logic ( HIGH to turn

Using the 4-channel relay module library for Proteus is straightforward. Here are the steps to follow:

Most modules use optocouplers to protect microcontrollers from high-voltage spikes.

To add this module to your Proteus software, follow these steps:
