This project demonstrates how to control a common cathode Tricolor (RGB) LED using an Arduino. The LED is programmed to cycle through its primary colors—red, green, and blue. A push button is then ...

This example code is in the public domain. https://www.arduino.cc/en/Tutorial/BuiltInExamples/Debounce // constants won't change. They're used here to set pin numbers ...

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 ...

There is an example of a programme that differentiates between long and short push-button pushes on the Arduino.cc website, but I was not taken it. However their was an example I did like the look of, ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

An innovative engineer can solve a problem in a complicated industrial environment with a few low-cost electronic modules and some Arduino programming. You can use this wireless emergency push button, ...

[Lars] shows you how to get a perfect score on the first four levels of BIT.TRIP RUNNER by using an Arduino to time and send button presses. This is a pretty simple game that uses a couple of buttons ...

OK, year-old pop culture references aside [Kyle] dropped us a line to show us his tutorial on using interrupts with your Arduino. Given the single core nature of your average Arduino’s AVR you pretty ...
