Arduino is the brain of our PCB and is already pre-programmed. Your first task in the book is to activate the Arduino! Here is a video on how we can activate the Arduino.

Now that you have fulfilled your task let’s learn something out of the box!

Below you would see the code which has been implemented in our Arduino.

#include <avr/io.h>  //gpio setup
#include <avr/interrupt.h> //for interupt service routines
#include <util/delay.h> // here the delay function is found
#include <stdio.h> // for printf and stuff
#include "usart.h" // serial communication

int main(void){
    int state = 0;
    DDRD = 0xFF; // FOR LED
    DDRC = 0xF0; // FOR BUTTON
    DDRB = 0xFF;
    PORTD = 0x00;
    PORTB = 0x00;
    PORTC = 0x3F;
    while (1){
        PORTD = 0b11111000;
        if(PINC==0b00111111){
            PORTB = 0b00000000;
        }
        if(PINC==0b00111101){
            
            PORTB = 0b00000001;
        }
        if (state == 0){
            if(PINC==0b00111110){
                PORTB = 0b00000010;
                _delay_ms(2000);
                state = 1;
            }
        }
        if (state == 1){
            if(PINC==0b00111110){
                PORTB = 0b00000100;
                _delay_ms(2000);
                state = 0;
            }
        }
    }
}
