Serial Lighting Control
All the play field lights are Neo Pixels, or driven by WS2811 chips. The asynchronous protocol is better suited to the long wiring runs than clocked protocols like IIC or SPI.
This shows the first live score display test. Thinking the blue 7-segment looks pretty cool. The display board is custom designed using WS2811 driver chips - the chip inside Neo Pixels. This allows the score displays to be daisy chained together significantly reducing the wiring.
We are using the BeagleBone Black single board computer to run just about the entire machine. The goal is to have the machine operate without a host PC.
