Let's work as a group on a micro-controller project!

We are building a new LED notification board for the workshop, adapted from Solexious' project. We're using this project as a learning platform for the new Not Just Arduino members.

We had interesting discussions & contributions from Jasper, TimS, Sue and Artag, everybody welcome to contribute.


- 4 x DE-DP10XV110 Green LED Dot Matrix available in the space

What extra functionalities do you want to add to the actual board?

  • Provisioning a network cable to the board can be a pain and that's just to send a few bytes of data every now and then. We can use the Nordic nrf21 chips (same as in EMF badge) to send the data wirelessly and cheaply. There is a good guide online. We will require a simple server/client setup.

digraph rfboard{
  IRCCAT [shape=box];
  sender [label="Arduino sender",shape=box];
  receiver [label="Arduino receiver",shape=box];
  board [label="LED board",shape=box];
  IRCCAT-> sender;
  sender-> receiver [label="RF"];
  receiver -> board;

} </graphviz>
