The Arduino WS2812b Controller Shield is a shield designed to offload the implementation of the WS2812b protocol to the shield. It is implemented on an ATtiny85, and the Arduino communicates with the shield over standard SPI. The code for the ATtiny85 can be found at https://github.com/k3jph/ws2812b-spi-controller

Welcome to your new project. Imagine what you can build here.

This project involves the design and implementation of a motor control circuit using an L298N motor driver IC and a Seeed Studio XIAO ESP32S3-Sense microcontroller. The motor driver operates a single DC motor ($M1$) with control signals provided by the microcontroller. Additionally, the project includes a WS2812B-B addressable RGB LED, enabling visual feedback or status indication. Primary goals: - Control the speed and direction of the DC motor using the ESP32S3 microcontroller. - Provide status indication via the RGB LED.

Production-intent ESP32-C6 controller for WS2812B/WS2815 addressable LED strips with 5V/10A input protection, strip high-side switching, 5V data level shifting, user buttons, and antenna keepout requirements.
