Transforming Motion into Color — My ESP32 Bluetooth Sync Project

Описание: Control NeoPixel Colors with Hand Motion | ESP32 + MPU6050 + Bluetooth Project

In this project, I used two ESP32 boards, an MPU6050 motion sensor, and a NeoPixel RGB LED to create a wireless motion-controlled color system.

What happens?
Tilt your hand — and the LED on the second ESP32 changes color in real time based on the motion!

Left tilt = Red

Right tilt = Blue

Forward/Backward tilt = Green

The center mixes all colors dynamically


How it works:

The master ESP32 reads roll & pitch data from the MPU6050

It maps the motion to RGB values

Sends them via Bluetooth to the slave ESP32

The slave updates the NeoPixel color and shows the current color on an OLED screen


Perfect for anyone exploring IoT, sensor-based interaction, or Bluetooth communication between microcontrollers.

Tools Used:

ESP32 (Master + Slave)

MPU6050 Gyroscope & Accelerometer

Adafruit NeoPixel

SSD1306 OLED

Arduino IDE
