The Science behind mixing drinks?

Web Interface

vue.js, webpack, pug

Backend

NodeJS, Tiny Router

Pump Control

Tessel API, GPIO

100% JAVASCRIPT

Tessel 2

(webdevelopers <3 hardware)

Tessel 2

MIPS 580mhz (your app runs here)
48mhz SAMD co-processor (realtime, arduino)
64mb RAM
32mb Flash
802.11 b/g/n wifi
Ethernet
2x USB
14 pins (GPIO, I2C, etc)

What does it look like?

// Import the hardware library
var tessel = require('tessel');

// Turn a LED on before the loop.
tessel.led[2].on();

// Blink!!!
setInterval(function () {
  tessel.led[2].toggle();
  tessel.led[3].toggle();
}, 100);

console.log("Pisca! (Press CTRL + C to interrupt)");

Development Workflow

Plug the board.
Try scripts using T2.
Write final version.
Upload final version.
Done.

Why the Tessel is cool?

It is JavaScript!
It is JS IN A TINY BOARD!!!
Favors iterative learning.
High Level API.
Very active community!
