This week I successfully got the same logic that I was using an Arduino Uno 3 for to work on the Raspberry Pi 4. This includes the move suggestions and starting and ending sequences. Hopefully this makes it easier to write code that can communicate with the computer vision system and chess engine since I can write code in Python now. I also verified that the wiring of my LEDs would work under the board and that I would indeed have to use my LED connectors instead of bending the LED strips under the board with Yoyo’s printed prototype of the board. An image is attached below.
My progress is on schedule. Next week I hope to get the hardware complete. The board printing and engraving is set to be complete the start of this next week so I hope to have attached all the LEDs under the board by the end of this week. I also hope to use this new set up to verify that my move suggestions are correct since I can have an easier time seeing them light up under the grid now.
