Xmas tree with sound-controlled LED animations

Posted on Thursday, December 20th, 2012 in ARM, Holiday by DP

Sound controlled LED light show for your Xmas tree.  An STM32 microcontroller takes instructions from a PC via Bluetooth and animates the LEDs.

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.
