Over the last few weekends and then some, I have been playing with the Colorific RGB Bulb from Amazon. Inspired by this learn guide https://learn.adafruit.com/reverse-engineering-a-bluetooth-low-energy-light-bulb/explore-gatt I decided to make it reactive to audio. Finally! An excuse to buy the Teensy Audio shield! Here are a few pictures and a short demo of it in action. You can find the code and my notes on the issues with it and where the project is at currently on:https://github.com/FriedCircuits/Jamrific Teensy 3.1 with Audio Shield, TFT connect to RPi Raspberry Pi 2 with BT 4.0 and UART connected to Teensy 3.1.
