Relay with PIC18F4520 Starter Board

Code

	#include "gpio.h"
	#define Relay PD_0 // Relay is connected to PORTD.0
	#define SW1 PD_2 // Switch is connected to PORTD.2
	/* start the main program */
	void main()
	{
	uint8_t value;
	GPIO_PinDirection(SW1,INPUT); // Configure the switch pin as Input
	GPIO_PinDirection(Relay,OUTPUT); // Configure the Relay pin as OUTPUT
	while(1)
	{
	value = GPIO_PinRead(SW1); // Read the switch status
	GPIO_PinWrite(Relay,!value); // ON/OFF the Relay as per switch status
	}
	}
