“The only challenging issue is the incompatible voltage level of the two boards”
In this second instalment, we will see how we achieved the same consistent result playing chess with Arduino UNO R4 Minima, the cheaper version of the new Arduino board, without the LED matrix display and the ESP32 S3 on the board.
While Enrico was developing the software implementation on the Arduino UNO R4 WiFi, Luis worked to create a sort of ‘advanced’ Minima board. The main problem of the Minima version concerned the inability of managing a WiFi connection, which, in the WiFi model, is covered by the ESP32
