Introduction
Provide smart lighting to a home using an RGB LED strip and an ESP32. The ESP32 will expose a BLE server that can receive commands from any BLE client. To prove functionality I implemented some simple features such as selecting from a number of preset colors and adjusting brightness.
Hardware
- ESP32-WROOM-32: 1 x ESP32 Sparrow development board
- NeoPixel LED Strip: 1 x 5m NeoPixel LED strip, 300 LED's.
- Breadboard: 1x Breadboard for securing connections.
- Connecting Cables
- USB-A to micro USB cable

Actual Hardware
The NeoPixel LED strip need +5V and GND to power the LED's and the addresing is done using a single data pin, which I have connected to GPIO 17.
Software
- Arduino IDE for development
- Adafruit_NeoPixel library for easy LED strip manipulation
- ArduinoBLE library for Bluetooth service.
