node-dimensions

Lego Dimensions Toy Pad library for NodeJS.

Installation

  npm install node-dimensions --save

Usage

Load the module

  var dimensions = require('node-dimensions');

Connect to a device

Construct a new device and connect to it:

  device = new dimensions.Device();
  device.connect();

Optionally, listen for the device to connect:

  device.on('connected', function() {
  });

Listen for minifig scans

Listening for minifigs scans can be done by registering an handler:

  device.on('minifig-scan', function(event) {
  });

Notes:

• The identity of a minifig can be checked via the minifig property. For example: event.minifig == dimensions.Minifig.BATMAN.
• Events are received when a minifig is added or removed from a panel. The action event property specifies either dimensions.Minifig.ADD or dimensions.Minifig.REMOVE
• The panel property specifies on which panel the scan occurred. This can be one of dimensions.Panel.LEFT, dimensions.Panel.RIGHT, or dimensions.Panel.CENTER.

Update panel LEDs

Panel LEDs can be updated using the following:

  device.updatePanel(panel, color, speed);

Arguments:

• panel - The panel to be updated, can be one of dimensions.Panel.LEFT, dimensions.Panel.RIGHT, dimensions.Panel.CENTER, dimensions.Panel.ALL.
• color - The RGB color of the panel. For example: red would be 0xFF0000 while 0x000000 would turn off the LEDs.
• speed - An optional parameter specifying the speed with which to update the panel LEDs. 0.0 is the slowest update speed available, while 1.0 is the fastest.
