Turn on the LED to the switch using codevision AVR.

This post, I will provide a tutorial for ATMega 16 microcontroller based LED lights  with a push button input using CodeVision AVR compiler software.

First we create a simulation in proteus, as shown below :

LED lights, I connect with port C0-C7 on ATmega16 microcontroller. Push button connected to the port A0.

Setting codevision same as the previous post about LED light using Code Vision AVR.

type the following syntax :

while (1)

      {

      // if the push button is pressed on PINA.0 (short to VCC) LED on PORTC will shift right.

      

      if(PINA.0 == 1)

      {

      PORTC=1;

      delay_ms(100);

      PORTC=3;

      delay_ms(100);

      PORTC=7;

      delay_ms(100);

      PORTC=15;

      delay_ms(100);

      PORTC=31;

      delay_ms(100);

      PORTC=63;

      delay_ms(100);

      PORTC=127;

      delay_ms(100);

      PORTC=255;

      delay_ms(100);

      }

      }

}
