RP2040-based Pi Day bling triggered by voice #PiDay #RP2040 @Raspberry_Pi

A new piece of RP2040-based bling bu Sai Yamanoor that changes its LED color when it detects one of three keywords being spoken: “Pi”, “3.14”, or “Irrational”.

This project describes a bling designed around the RP2040 microcontroller. In the spirit of celebrating Pi-Day, it is designed to capable of detecting three words namely: Pi, 3.14, and Irrational. When it detects one of these keywords, the RGB LEDs on the bling change their color.

The bling is designed around the RP2040 microcontroller. The components on the front side of the bling include 12 WS2812B individually addressable RGB LEDs and 48 RGB LEDs.

The bling was programmed and tested in two ways:

  • Using Arduino IDE
  • Using Raspberry Pi Pico C/C++ SDK
