Project:LED Notification board2
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.
Specs:
- 4 x DE-DP10XV110 Green LED Dot Matrix available in the space
What extra functionalities do you want to add to the actual board?
>>>> Please add below: your links, suggestions, code, specs on the project page
- 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.
