node-nxt

Node.js interface to pbLua running on a Lego Mindstorms NXT device.

Node-NXT

Node-NXT is a Node.js project that can be used to contol a Lego Mindstorms NXT device that is running pbLua.

Node-NXT mirrors the NXT API of pbLua, enabling you to write scripts to control the device in JavaScript.

How to Install

npm install node-nxt

How to use

First, require node-nxt:

var nodeNxt = require('node-nxt');

Next, connect to the device using USB port or Bluetooth (USB in this example):

nodeNxt.connect ('/dev/cu.usbmodem621', function (nxt) {
    // ... 
};

Then use the value passed to the callback in much the same way as you would in pbLua:

    nxt.DisplayText ('Hello world.');

Use callbacks to retrieve returned values:

    nxt.TimerRead (function (time) {
        sys.print ('Time on nxt: ' + time);
    });
