The DFRobot Bluetooth 4.0 RGB LED Strip Kit combines a 3-metre WS2812 addressable LED strip with a Bluno (Arduino-compatible Bluetooth 4.0 board), sound sensor, and audio analyser. Control every individual LED from your iPhone or Android device via Bluetooth Low Energy — change colours in real time, create animations, or react to music with the built-in spectrum analyser.

The kit uses WS2812 individually addressable LEDs at 60 LEDs per metre, giving you full per-pixel colour control. The LED strip can be cut and divided into separate sections for use across multiple projects.
