We’ve been working hard recently on the electronics and control system for Version 2 and thought we would share the LED ring we have made for the drinks tray.
This will illuminate the glass and drinks tray, it is made from two strips of 18 WS2812 RGB LEDs back to back. Each LED is individually controllable with PWM. The advantage of using these strips is that we can interface it with just 3 wires: 5V, ground, and one data pin.
The video shows shows it running a basic test sequence from an Arduino nano using the FastSPI library.
