- Technologies: Infrared sensing, STM32 Microcontrollers, UART, WS2812 LEDs
Details
Reactive light system that illuminates 512 RGB LEDs around any object on the staircase. Uses 11 STM32 microcontrollers communicating over UART to process readings from 64 infrared sensors. Each of the 512 RGB LEDs is individually addressable. Modular, PCB-based system is modular to allow for simple expansion or application to other use cases.
