# Gesture LED Control

Day 81 of the 100 Days 100 IoT Projects collection. Board: XIAO.

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
