Now that your setup has been completed, move into the main loop of your code. When your button is not pressed, the internal pull-up resistor connects to 5 volts. This causes the Arduino to report "1" or HIGH. When the button is pressed, the Arduino pin is pulled to ground, causing ...

For the full Arduino code, you can headhere Summary That’s all for today on pull-up resistors. I hope with today’s blog, you get a deeper understanding of what is a pull-up resistor, the differences between pull-up and pull-down, alongside interfacing with an Arduino board! Remember,...
If you run this code and open the Serial Plotter, you’ll see that the default value is 1 (HIGH). When you press the button the state directly goes to 0 (LOW) and comes back to HIGH when you release the button. Well now it’s much better. Problem solved!

Since pull-up resistors are so commonly needed, many MCUs, like the ATmega328 microcontroller on the Arduino platform, have internal pull-ups that can be enabled and disabled. To enable internal pull-ups on an Arduino, you can use the following line of code in your setup() function: ...
However,don’t get too clever with the source code, as the Arduino compile chain pretty much assumes you’re not doing exotic language tricks. It’s a great way to make stuff work, that’s for sure! 2011-07-31 daggilliDavid Gillies ...
