Basically, when you plug a push button to a digital pin, the value the Arduino reads is between 0V and 5V. If the value is close to 0V, you will get LOW in your code, and if it’s close to 5V, you will get the value HIGH....
So assuming we want to detect the morse letter V, which is ··· ⎯ in morse code. if (myButton.event(DIT, DIT, DIT, DA)) { Serial.println("V for Victory !"); }About Button library for Arduino. The usual, plus "if (button.event(LONG, SHORT, LONG))" and more. Resources...
This code tracks the state of the LED (is it on or off) and then tracks the button to see if it has been pressed. Upon pressing the button, the state of the LED is changed. /* ARDUINO BUTTON TOGGLES LED By: TheGeekPub.com More Arduino Tutorials: https://www.thegeekpub.com/ardui...

README Code of conduct License Security Arduino OneButton Library This Arduino library is improving the usage of a singe button for input. It shows how to use an digital input pin with a single pushbutton attached for detecting some of the typical button press events like single clicks, double...
From Arduino To HTML: The Need For A Pushbutton Component Before we embark on the journey, let’s explore what we are going to create, and more importantly, why. I’m creating an open-source Arduino simulator in JavaScript calledavr8js. This simulator is able to execute Arduino code and...
