In this video I’ll explain how to set up your Arduino and Duino so you can interact with your Arduino using nodejs (and javascript).

• The Arduino software package is downloadable from the Arduino website.
• You can find the Duino module here.
• Installing Duino is as simple as running npm install duino.

• My custom bleep function:

  var arduino = require(‘duino’),

  board = new arduino.Board();
  

  var led = new arduino.Led({ board: board, pin: 13 });

  var bleep = function() {

  led.on();
  setTimeout(function() {
      led.off();
  }, 100);
  

  }

Troubleshooting:

• You need a recent version of nodejs (0.4.x was not working) for the Duino module.
• If you can’t upload the Arduino program, make sure the right model is selected at Tools -> Board.
