Gesture LED Control

Lighting · Board: XIAO · Day 81 of 100

Wave your fingers — OpenCV tracks gestures and toggles LEDs on the XIAO ESP32-S3. Camera vision meets embedded control.

How it works

A camera feed runs through OpenCV on the PC, which classifies your finger gestures and sends the result over serial to the XIAO ESP32-S3. The board just switches LEDs — the vision system does the thinking. Camera input, embedded output, one serial link between them.

What you'll learn

  • Computer vision input
  • Gesture classification
  • Vision-to-embedded bridge
  • Serial result passing
