The idea for this project came as I wanted to add some backlight to my computer and desk so that it would be more cozy especially during the night. I wanted to be able to have more mods and have a finer control on the LEDs, so I chose a NeoPixels LED Strip, where I can control each LED of the Strip individually.

For the communication protocol between the ESP32 controller and my phone, I decided to use the Bluetooth LowEnergy protocol. I will use my phone as a remote control to send commands to the ESP32 controller and control the LED strip.

I used an OLED display as a way to better visualize the current status of the system, like if there is a device connected, if the lights are turned on or of, and what mode is currently selected.

• ESP32-WROOM-32: 1 x ESP32 Sparrow development board (purchased from here)
• NeoPixel LED Strip: 1 x 5m NeoPixel LED Strip (became 4m after an accident ) (300 NeoPixel LEDs for 5m or 270 NeoPixel LEDs for 4m)
• Breadboard: 1 x 830 holes Breadboard
• OLED Display: 1 x 0.91inch OLED Display
• Connection Cables
• USB-A to MicroUSB Cable

• Arduino IDE for code development and Serial Monitor
• BLE Scanner Android App for connecting my phone to the ESP32 board via BLE
