Here's an example of using the 4 Channel Relay Module to control a motor:

// Simulation code for controlling a motor using the 4 Channel Relay Module
#include < proteus.h>
#define RELAY_PIN  D0
void main(void)
// Initialize the relay module
    relayInit(RELAY_PIN);
// Turn on the motor
    relayTurnOn(RELAY_PIN, CHANNEL_1);
// Delay for 5 seconds
    delay_ms(5000);
// Turn off the motor
    relayTurnOff(RELAY_PIN, CHANNEL_1);

Many users download the library, yet Proteus throws an error: "Unknown part name '4CH_RELAY'".

Here is how to fix it:

If no library works, build your own macro in 5 minutes:


Even with a perfect library, simulations fail. Here are the top 3 errors:
