sloooo Microcontrollers are slow. HALFSTACK VIENNA

“ JavaScript on microcontrollers? Are you crazy? Me – two years ago HALFSTACK VIENNA
Microcontrollers are very power efficient. HALFSTACK VIENNA
Microcontrollers only need to be fast enough to solve the probem. HALFSTACK VIENNA
Microcontrollers do not have an need 45 operating seconds tosystem. boot. HALFSTACK VIENNA

Building an IoT device feels out of reach to a lot of web developers. Most of us didn’t study electrical engineering, and never learned to solder. And programming a microcontroller is on a completely different level than building a website.
But that is just not true anymore. Nowadays microcontrollers have become powerful enough to run JavaScript. And that opens up IoT to all of us. With just 20 lines of code we can build a connected lightbulb, and within seconds we can wirelessly deploy it. Write a couple of lines more, and you can even remotely control a car. And that is precisely what we are going to do.
The following resources were mentioned during the presentation or are useful additional information.
In the demo’s I used WebBluetooth to talk to the lightbulb, pixel matrix and car. This article explain all the basics of Bluetooth and the WebBluetooth API.
Here’s what was said about this presentation on social media.
