We tried to connect and display a message on the 8X2 LCD screen through the ESP32, but it did not work for several reasons:

• the ArduinoIDE app doesn't detect any screen
• the ESP32 is really complicated to handle since the wires leave all the time and the screen is glitching a lot since the power is not well fixed/delivered to it

We will try again after researching even more.

For the box, we're thinking about the mechanism to open and close it.

We're thinking of a lock like a chest or a screw process.
