<div><p>This practical book shows you how to build web applications that connect devices to the Internet of Things, using JavaScript and the Node.js platform. Programming Arduino boards in C or C&#43;&#43; is great for quickly prototyping and exploring embedded systems, but if you want to control or monitor hardware from web browsers, you need to start speaking JavaScript.</p><p>Web browsers make excellent interfaces for hardware, because they come on every system, make serial communication convenient, and provide a screen, which many embedded systems often don’t have on their own. Using the browser as the interface, JavaScript and Node.js provide communication between applications and hardware.</p><ul><li>Learn how to use web browsers as interfaces for embedded hardware</li><li>Understand basic messaging between Node.js applications and hardware with Sockets’ publish-and-subscribe pattern (messaging is key for IoT)</li><li>Use libraries to work with bits and bytes in Node.js</li><li>Get examples for interactive hardware devices with Node.js and Johnny-5 (this shows how JavaScript can simplify hardware prototyping)</li><li>Learn how to use a single-board computer (SBC) and/or Tessel to run scripts inside embedded devices (these devices can act as backbone for home automation, communication, and robots)</li></ul></div>
