Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

A simple game using Arduino Uno, 16x2 LCD and a push button. In this tutorial, you are going to learn about interfacing the button with Arduino using the Arduino digitalRead function. There are a lot ...

Last time, we read the state of a push button using a pull-down circuit with a 10kΩ resistor. This time, we will use the "pull-up resistor" built into the Arduino. This is a convenient method that ...

How to 3D print a case for a ESP32-C3 microprocessor and 1.8in TFT Display/Rotary Enc/Switch module for under $15 Build a DIY ropeway working model using a push button, relay, buzzer, 5V DC motor ...

Last time, we used Arduino's INPUT_PULLUP to read the state of a push button without using external resistors. However, with mechanical buttons, it can sometimes appear as if the button was pressed ...
