A Bluetooth Controlled LED Strip Project

Lumos

A Bluetooth Controlled LED Strip Project. It uses an ESP32 microcontroller to drive a 1M strip of 60 WS2813 LEDs. The project is controlled via Bluetooth using an Android app and supports multiple effects out of the box

Getting the parts

• ESP32 Dev Kit
• WS2813 Strip
• Jumpers
• Power Supply

Connections

• DATA pin to GPIO 19
• V _in and GND to their respective pins

Getting Started

• compile and load lumos.ino onto the ESP32

Note

Although the LED strip can be driven using power from the ESP32, it's not advisable to do so for long periods of time or for a large number (>60) of LEDs. I have tested this with a 1M strip having 60 LEDs which works fine but, it's good to have a separate power supply to drive both the ESP and the strip. At max brightness, each LED can draw about 60mA which results in a maximum current draw of 3.6A. This is way beyond what a microcontroller's terminals can handle.
