About the Hub
The HUB is a circuit board with eight RJ ports, designed to connect various projects through them. The only constraint is the communication: it allows a strict protocol containing only numbers from 0 to 99. This allows to connect projects from very different forms together. Then a HUB is connected to other HUBs over the internet, enabling long distance interactions. This project is open-source, you can find all the details on how to make your own on the GitHub link below.
