Interfacing of Push Button With ATmega16

In this tutorial, we will learn how to interface a switch(push button) with ATMEGA16 using AVR studio. In the previous video, we learnt how to interface LEDs with ATMEGA16 using AVR studio.
The push-button is a component that connects two points in a circuit when you press it. The example turns on an LED when you press the button. Here we have connected two push button to PORT C in PC0 & PC1. And for LEDs connection please refer my previous blog.

Components Required:-

AVR Controller(Atmega16)
LEDs
Push Button
Connecting Wires
USBASP Programmer

Dump the following code after connection and select chip ATMEGA 16.
#include<avr/io.h>
#include<util/delay.h>

void main()
{
   DDRB=0b11111111;
   int S1;
   int S2;

   while(1)
   {
    S1=PINC&0b00000001;
    S2=PINC&0b00000010;
    if(S1==0b00000001)
    {
    PORTB=0b00000001;
    _delay_ms(100);
    }
    if(S2==0b00000010)
    {
    PORTB=0b00000010;
    _delay_ms(100);
    }
   }
   }

After generating the hex file from AVR Studio, flash it in the chip and the following output can be seen.

Getting Started with Arduino

What is Arduino? Arduino is basically an open source electronics platform which is having easy to use hardware and software implementation. It’s a micro-controller interfaced with other vital components like programmer ICs, voltage regulator etc. With the help of this, we can interface various input (sensors) and output (LED's) components. Why Arduino? Arduino is not just a micro-controller it is also interfaced with several other components which make the job of the user very simple. Arduino Uno Pin-Out How Arduino works? An input of 5v is given to the board using a USB cable (not necessary) through a laptop or any other convenient power source. Microcontrollers are usually programmed through a programmer unless we have a firmware in our microcontroller that allows installing new firmware without any external programmer. This is bootloader. All the controllers present in UNO are from ATMEL Semiconductor (Now acquired by Microchip). We hav...
