    How to Install

    Follow the installation instructions detailed here

    We've provided a repo containing an example cylon-tessel project.

    $ git clone my-tessel-project
    $ cd my-tessel-project
    $ npm install
    $ tessel run blink.js

    If the blue light starts to blink, then you're all set!

    How to Use


    This small program lets you toggle an LED on and off.

    var Cylon = require('cylon');
      connections: {
        tessel: { adaptor: 'tessel' }
      devices: {
        led: { driver: 'led', pin: 1 }
      work: function(my) {
        every((1).seconds(), function() { my.led.toggle() });


    This small program shows how to use the Tessel Climate module.

    var Cylon = require('cylon');
      connections: {
        tessel: { adaptor: 'tessel', port: 'A' }
      devices: {
        climate: { driver: 'climate-si7005' }
      work: function(my) {
        my.climate.on('error', function (err) {
        every((1).seconds(), function() {
          my.climate.readHumidity(function (err, humid) {
            console.log('Humidity:', humid.toFixed(4) + '%RH');
          my.climate.readTemperature('f', function (err, temp) {
            console.log('Degrees:', temp.toFixed(4) + 'F');

    How to Connect

    As mentioned in the How To Install section, connecting to the Tessel is easy. You just need to follow the provided instructions on the Tessel site.

    If you've already done this, your Tessel should already be connected and ready to run Cylon.JS code.

    Tessel Module Support

    The Tessel has a variety of custom hardware modules specifically for use with Tessel. Cylon.js has support for the following Tessel modules:

    • GPIO <=> Drivers

      • Analog Sensor
      • Button
      • IR Rangefinder
      • LED
      • MakeyButton
      • Maxbotix Ultrasonic Range Finder
    • I2C <=> Drivers

      • BlinkM
      • BMP180
      • HMC6352 Digital Compass
      • LCD
      • MPL115A2 Barometer/Thermometer
