This repository contains the code used during the HamOnt JavaScript talk on May 30th of 2019 about real-time communication with WebSockets and a Raspberry Pi by Jenifer Champagne.

Folks of all JavaScript-related interests and skill levels! Please do feel welcome to go to a meetup if you're int he area!
- It looks like the
asyncvsPromiseconflicts I mentioned were likely specific to BluebirdPromises
This code was designed for use with a RaspberryPi. Unfortunately several GPIO (General Purpose Input/Output) node modules were using outdate libraries which were not compatible with the Raspberry Pi 3B+ used in the demo. As such, the wiringpi command line utility (gpio) was used as it was compatible with the device used.
- Install WebSocket node module
npm install - Launch the WebSocket server while initialising the GPIOs
npm start
Note: This will not work on a system without the GPIO / wiringpi utility. If you are on a Raspberry Pi system and find yourself without the utility, you can install it with the following command: sudo apt install wiringpi -y
