Here, pull-down resistor is maintaining the logic of the input pin near zero. In the loop function, I am reading the status of the input pin, saving it to the variable and passing to the LED pin. In this program, I have given all the declaration in the setup function.

So, in setup function, we have to declare things only because it is only going to execute only one time, but in loop program written in the loop, a function is going to execute until the microcontroller is powered. In Arduino, every program had two functions, a setup function, and a loop function. The program is pretty much straightforward. Push Button Debouncing.īelow is the schematic that I have used, notice that I have introduced a pull-down resistor when the Switch is not connected to the Vcc.

To use a push button switch with a microcontroller, first you should configure the corresponding pin as input. In most of the embedded electronic projects you may want to use a push button switch to give user inputs to the microcontroller. This tutorial is meant for beginners in the field of Atmel AVR programming.
