Christmas Tree with 404 Individually Controlled LEDs via Bluetooth

Olivier St-Martin Cormier got into the Christmas spirit this year by bringing his tree to life with LEDs that can dance to the music. He is using a stm32 microcontroller to get the job done.  You can see a video of it in action below.

This is my Christmas tree, it has over 400 lights (exactly 404) that are all individually controlled by an STM32 microcontroller. The computer plays the music and processes the sync track for the lights and send the state of the tree to the stm32 over bluetooth. The pc-side controller has a web interface, so the whole tree can be controlled from any browser (pc/phone/tablet). This is still in “beta” stage (I will add more types of animations) but it still serves its purpose well.”
