After some debugging, I have figured out what was the issue with the lamp matrix controller board. I was multiplexing it too fast. By lowering the frequency of multiplexing, I got the board to properly work.

Next step is to map the palette events from Pinball Fantasies into lamp on / lamp off commands for the Arduino.

Then I need to fix an issue with the intensity of lamps when they are turned on simultaneously.
After that, I need to try I2C or some other communications protocol and then build 3 more of these boards for controlling the whole playfield.

  1. Olá! Eu acredito que uma solução seria utilizar relés para o acionamento das lâmpadas. Assim a corrente de comando não seria (não precisaria ser) a mesma corrente que alimenta cada uma das lâmpadas.
