Initial Prototype
While initially running this on a bread board, I learned how the mini screen worked and how to use the necessary libraries.

All the Components Together
I hand soldered all the components to a solderable breadboard. Here we can see the miniscreen, the bluetooth module, and the Seeeduino Xiao micro controller.

Program
This is a drawing program that I wrote for it. At the top you can see "<-", P, E, C, S.
- <- : Back to games menu
- P : Pen mode
- E : Erase mode
- C : Clear screen
- S : Send Drawing
Drawing App
Bluetooth
This is the result of sending a drawing over bluetooth. My laptop had a program listening to a bluetooth socket and when recieving bytes, it prints them in Ascii to the terminal.

Conclusion
This was a super fun project to work on and I learned a lot about how to build complex interactions directly on top of hardware constraints.
