PLUG & PLAY MODULE ECOSYSTEM

PROTOTYPE FAST WITH MODULAR HARDWARE.

Interact with the physical world from sensing to actuation to connecting with other devices. Each module has an open source library on NPM, with instructions and tutorials available online. It's literally plug, npm install, and play.

BUILD YOUR APPLICATION IN MINUTES.

Tessel 2 runs JavaScript and supports NPM (the Node package manager)— that's HTTP, Twitter, web server, color, and async right out of the box.

Install

npm install tessel -g

Add Library

npm install ambient-attx4

Get Online

tessel wifi -n [ssid] -p [password]

Tessel 2 also has the capacity to support multiple languages– see samples of Rust and Python in the tabs below.

JavaScript

Python

Rust

/* ambient.js example */

// this example streams sound data from // the ambient sensor every 0.5 seconds var tessel = require('tessel'); var ambientlib = require('ambient-attx4'); var WebSocket = require('ws'); // Connect to our ambient sensor. var ambient = ambientlib.use(tessel.port['A']); // Open a websocket to our app. var ws = new WebSocket('ws://awesome-app.com/ambient'); // When the connection is established ws.on('open', function () { setInterval(function () { // read some sound level data ambient.getSoundLevel(function(err, sdata) { if (err) throw err; sdata.pipe(ws); }) }, 500); // The readings will happen every .5 seconds });

Use your favorite text editor and libraries to program Tessel 2, just like any web development environment. Uploading new code is as easy as tessel run!

Run Code

tessel run ambient.js

USB MODULES

Tessel has two USB ports. Plug in USB modules and control them with a simple script.

JavaScript

Python

Rust

/* ambient-camera.js example */

// this example records video from a camera // when a certain sound level is reached var tessel = require('tessel'); var http = require('http'); // set up camera var cameralib = require('camera-usb'); // set up ambient sensor on port A var ambient = require('ambient-attx4').use(tessel.port['A']); // set a sound trigger ambient.setSoundTrigger(0.6); cameralib.find(function(camera) { // stream some video when sound is sensed ambient.on('sound-trigger', function(){ var req = http.request({ hostname: 'example.com', path: '/upload', method: 'POST' }, function (res) { res.pipe(process.stdout) }); camera.captureStream(2000, 'mjpg').pipe(req); }); });

Combine USB and 10-pin modules and run them with the same script.
