Internet of (JavaScript) Things

Why do you need low-level programming experience, hardware hacking skills and the ability to speak hexadecimal to build applications for the "Internet of Things"? Can’t we just use JavaScript?

Actually, you can!

This session will introduce the open-source tools for “wiring” the Internet of Things using JavaScript. Once we’ve learnt to control hardware devices from JavaScript, we’ll show you how to use these tools to build applications combining hardware devices with web APIs. We'll explain the messaging protocols that allow us to connect remote devices over the Internet before demonstrating how to use the cloud for scaling applications to support thousands of simultaneous devices.

This practical session will teach developers the tools, platforms and protocols needed to create "Internet of Things" applications powered by JavaScript. If you want to build applications connecting devices without breaking out the soldering iron, this session will show you how!

25. HOW DO WE CONNECT REMOTE DEVICES? “Museum of Communications” by Adam Foster https://flic.kr/p/dtwgV7
26. “MQTT is a machine-to-machine (M2M)/Internet of Things connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium.”
