The Tessel is tiny

Its modules too

Modules

▪ Accelerometer▪ Ambient Light +

Sound▪ Audio▪ Bluetooth Low

Energy▪ Camera▪ Climate▪ GPS

▪ GPRS▪ Infrared▪ MicroSD Card▪ nRF24 Module▪ Relay▪ RFID▪ Servo

Node.JS for IoT

▪ Lots of projects around controlling hardware in Node.JS– Real-time event processing– Simpler than C/C++– Native connectivity– Lots of modules to reuse

▪ Some examples– https://

Listen for Ambient module events

var tessel = require('tessel');

var ambientlib = require('ambient-attx4');

var ambient = ambientlib.use(tessel.port['A']);

ambient.on('ready', function () {

ambient.setLightTrigger(0.5);

ambient.on('light-trigger', function(data) {

console.log("Our light trigger was hit:", data);

});

});

function upload_picture(name, image) { var options = { hostname: blob_host, port: 443, path: '/' + blob_container + '/' + name + blob_sas, method: 'PUT', headers: { 'Content-Length' : image.length, 'x-ms-blob-type' : 'BlockBlob', 'Content-Type' : 'image/jpeg' } };   var req = https.request(options, function(res) { res.on('data', function(d) { process.stdout.write(d); }); });

Face Detection with Project Oxford

• Tessel + Camera module• Take a picture on button press• Upload the picture to Azure

Blob Storage• Query Project Oxford Face API,

using Blob URL• Get a response back with face

attributes like gender and age• Identify faces!
