Raspbery Pi 3 + Node.js and Two Push Buttons

[cloudraider]

Hey there,
I am new to this Forum so I hope that I am in the right place.

I have the following idea:

I want to connect two buttons to my Raspberry Pi 3 and trigger functions on my Node.js Sever when pressed.

Code: Select all

var Gpio = require('onoff').Gpio; //include onoff to interact with the GPIO

var pushButton = new Gpio(17, 'in', 'rising', {debounceTimeout: 10});
var pushButton2 = new Gpio(18, 'in', 'rising', {debounceTimeout: 10}); 


pushButton.watch(function (err, value) {
//Watch for hardware interrupts on pushButton GPIO, specify callback function
  if (err) { //if an error
    console.error('There was an error', err); //output error message to console
  return;
console.log("Btn1");
});

pushButton2.watch(function (err, value) { 
//Watch for hardware interrupts on pushButton GPIO, specify callback function
  if (err) { //if an error
    console.error('There was an error', err); //output error message to console
  return;
  }
console.log("Btn2");
});

Below I have my wiring:

Now the Issue I am running into is, that whenever I press Button1 the Button2 is pressed as well and if i try to press Button2 it is not working 100% of the time, meaning if i press it around 5 times it registers one event.

Anyone any ideas?

Move the red wire to 3V3 or you could destroy your Raspberry.

You may have already damaged it irreperably.
