A project log for Light Link

A device which allows you to communicate with draw on a Matrix LED, drawing made with your phone

To summarize, each log will be posted on Thursdays since it's the day we have class and gather to review our progress, essentially a meeting. For example, this week, our dear Romain, as well as Rachel, have started a prototype each on their own:

Consisting of a LED Matrix (slightly oversized), an ESP 32 that serves as the bridge between our Matrix and the phone* (I'll explain the functionality later), and also displays whether the ESP is connected and a battery image to visualize where it will be placed. There's also a photoresistor to adjust brightness.

On the other hand, Florian has created about twenty 8 by 8 drawings to populate the library we'll offer to users for pre-made drawings.

Finally, on my end, I've started designing the website, with a loading screen, homepage, and a few menus.

*Regarding the ESP functionality, we've had debates on how our project should communicate with the web page. Our latest decision was to connect the ESP to the phone's network to always stay connected and receive messages at any time.

During the session, we began programming the website in HTML/CSS and brainstormed on further improvements and additions to the project's electronics and functionalities.

For the next session, we will continue with the web design and proceed with designing the PCB for the matrix.
