Micro:bit V2 Interactive LED Strip with Light Sensing

This project showcases how to create an interactive LED strip experience using a Micro:bit V2 board, a VEML6030 ambient light sensor, and a WS2812B addressable LED strip.

Features

• Multiple Modes:
  • Lights ON: LEDs display a static pattern, controlled by button B.
  • Lights OFF: All LEDs are turned off.
• Button Control:
  • Button A: Cycles through the different modes.
  • Button B: Changes the LED animation pattern (in Lights ON mode).
• Ambient Light Sensing: The VEML6030 sensor adjusts the brightness of the LEDs based on the surrounding light levels.
• WS2812B LED Strip: Utilizes the WS2812FX library for a variety of captivating LED animation patterns.

Wiring Diagram

Usage

1. Power on your Micro:bit V2.
2. Press button A to cycle through the modes.
3. Press button B to change the LED animation pattern (in Lights ON mode).
4. The LEDs will automatically adjust their brightness based on the ambient light.

Customization

• Adjust the VEML6030 sensor settings and brightness mapping in VEML6030.cpp to fine-tune the light sensitivity.
• Modify the LED animation patterns or add new ones in State.cpp and WS2812FX.h.
• Experiment with different motion detection thresholds and LED responses in main.cpp.
