LEGO Infrared

What is is?

LEGO IR is module that returns an infrared buffer. This can then be used in combination with Tessel to control LEGO Power Functions!

I've only managed to test this on Tessel as it's all I have. If you want any examples adding for other hardware or have tested it on other hardware let me know! (raise an Issue or PR!).

How do I use it?

var LegoIR = require('lego-ir');
var lego = new LegoIR({
  mode: 'comboDirect',
  channel: 1
});

var buffer = lego.move({
  outputA: 'forward',
  outputB: 'float'
});

// Send buffer to Tessel IR and watch your lego move!

Modes

ComboDirect

ComboDirect allows you to control two outputs at once on a single channel.

outputs

• outputA
• outputB

Move Options

• float
• brake
• forward
• backward

Payload Example

lego.move({
  outputA: 'forward',
  outputB: 'float'
});

Examples

Tessel IR

var tessel = require('tessel');
var infraredlib = require('ir-attx4');
var infrared = infraredlib.use(tessel.port['A']);

var LegoIR = require('lego-ir');
var lego = new LegoIR({
  mode: 'comboDirect',
  channel: 1
});

var legoBuffer = lego.move({
  outputA: 'backward',
  outputB: 'forward'
});

infrared.on('ready', function() {
  if(err) throw new Error(err);
  console.log("Connected to IR module!");

  setInterval(function() {
    infrared.sendRawSignal(38, legoBuffer, function(err) {
      if(err) throw new Error(err);
      console.log("IR Signal Sent!");
    });
  }, 500);
});
