In this post, I want to show how to measure the voltage up to 5V with an Arduino. Review In the article Arduino Lektion 4: LED mit Fotowiderstand I showed how to read the value of a photoresistor and “visualize” it via a light emitting diode. What we actually did is to measure the voltage…

If you build a pushbutton into your circuit, sooner or later you will encounter that it sends a signal more than once. This behavior is called “bouncing”. In the tutorial Arduino Lektion 33: Taster mit Pull Down Widerstand I already explained how to build a small circuit with a push button and a pull down…
