| + | Back in 2017 I produced two digital pinball machines controlled with real hardware flippers and tilt function. These machines were the Xero Pinball and Reload Bar Pinball tables. | ||
| + | |||
| + | The original boards were done on perf and were an eye-sore. But they featured USB HID keyboard functionality, allowing the lighting of LED indicators. | ||
| + | |||
| + | It was designed with good old pen and paper which was then used as the reference for designing the new PCB layout and connections in KiCad, then testing component footprints for sizing. | ||

| + | I recently picked up an ESP32-S2 based board that features an APA102 RGB LED which is a serial device with data and clock pins. | ||
| + | |||
| + | Working with this LED device seemed tricky at first, but thankfully a good datasheet made everything pretty clear. | ||
