A brand new piece of RP2040-based bling bu Sai Yamanoor that modifications its LED shade when it detects one in every of three key phrases being spoken: “Pi”, “3.14”, or “Irrational”.
This challenge describes a bling designed across the RP2040 microcontroller. Within the spirit of celebrating Pi-Day, it’s designed to able to detecting three phrases specifically: Pi, 3.14, and Irrational. When it detects one in every of these key phrases, the RGB LEDs on the bling change their shade.
The bling is designed across the RP2040 microcontroller. The elements on the entrance facet of the bling embody 12 WS2812B individually addressable RGB LEDs and 48 RGB LEDs.
The bling was programmed and examined in two methods:
- Utilizing Arduino IDE
- Utilizing Raspberry Pi Pico C/C++ SDK
