Prototyping IOT with JavaScript

Prototyping IoT devices is something that you may believe requires specialized skills in electrical engineering, embedded development, and mechanical engineering. Not so fast! Lance Gleason says that, thanks to the maker revolution, we can combine our deep knowledge of programming with access to a 3D printer and some basic electronics/soldering skills to create valuable prototypes. More importantly, there are now boards that give Javascript developers the ability to interact with them without requiring custom Bluetooth drivers and writing firmware. Join Lance for a quick tour of IoT prototyping options and then take a deep dive into how you can create a prototype, writing only Javascript code with devices such as the MbientLab MetaWear and Arduinos. This will be a hands-on session with live demos where you will see how to get started with these boards—and have some fun along the way. See how easy it can be to play with IoT and start to p rototype your ideas!
