Arduino Button - mit digitalRead() einen Knopf auslesen und eine LED steuern. Wie bei Arduino LED blinken lassen gezeigt, kann der kleine Mikrocontroller Ausgänge steuern. In Potentiometer auslese n haben wir gezeigt, wie das Auslesen analoger Eingänge funktioniert Now, we have to tell Arduino that we want to use a pin as an input. The command is: pinMode(buttonPin,INPUT); You realized it, yes? It is the same command we used for the LED. Just the argument this time is not OUTPUT but INPUT. To find out whether the button is pushed (HIGH) or not (LOW) we can use this command: digitalRead(buttonPin) To help with this I thought I would put together an Arduino based button box where the buttons should hopefully fall more easily to hand. As with some of my other projects, I chose to use an Arduino Leonardo due to the built-in USB Human Interface Device (HID) capabilities. I bought a plastic enclosure and some cheap buttons from Ebay which aren't brilliant so my recommendation is to buy better quality buttons. I used a bracket taken from an old wheel to mount the box to my desk

Okay, so let's get our arduino wiring up with a push button. So we can start writing some programs with it. First off let's connect the ground from the arduino and the power from the arduino, the 5 volts to rails on the breadboard, so that we can use them plug a wire into the ground. Pin on the Arduino I'll connect it to our left rail here and now do the same thing with 5 volt line so plug it into the connector marked 5 volts and we'll hook that up to the rail on the right. arduinesp.com. Webserver in Arduino with button to set led on and off. Saved by da This tutorial describes how to connect an Android app to Arduino using a Webserver that runs on Arduino.
