3 Different way of connecting a push button to Arduino 1 Comment / Arduino / By Najad / Arduino INTRODUCTION In this chapter, we are going to learn the three different ways of connecting a push-button with an Arduino microcontroller. Hardware Required ComponentsAmazon.inAmazon.comBanggoodAliExpressUtsourceArduino NanoPush Button Three Ways Internal pull-up resistorExternal pull-up resistorExternal pull-down resistor Internal pull-up resistor Connect the push button with Arduino as shown in the circut ie,Connect one terminal of the push button to any digital pin of Arduino in my case I’m using digital pin D5Then connect the other terminal of the push button to the ground of Arduino.Now upload the below code. Code Result By default, the pin state will be HIGH.When we press the push button the pin state will change to LOW. External pull-up resistor Connect one of the terminal of the push button to any digital pin of Arduino, in my case I have used digital pin 5.Connect the other terminal of the push button to the ground of Arduino.Then connect a resistor of value 10 Kohms from the digital pin which you have connected the push button to the 5v of Arduino, in my case I have connected the resistor form digital pin 5 to 5v.Now upload the below program. Code Result By default, the pin state will be HIGHWhen I press the push button the state will change to LOW. External pull-down resistor Connect one of the terminal of the push button to any digital pin of Arduino, in my case I have used digital pin 5.Then connect the other terminal to the 5v of Arduino.Then connect a resistor of value 10 Kohms from the digital pin which you have connected the push button to the ground of Arduino, in my case I have connected the resistor form digital pin 5 to ground.Now upload the below code. Code Result By default, the pin state will be LOWWhen we press the push button the state will change to HIGH from LOW Video To buy electronic components order from UTSOURCE Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on WhatsApp (Opens in new window)MoreClick to share on LinkedIn (Opens in new window)Click to share on Pinterest (Opens in new window)Click to share on Telegram (Opens in new window)
