Holiday Tree
Smart Holiday Tree with 26 LEDs
- Overview
- Driver
- Tethered
- Standalone
This is arguably the smartest holiday tree in the world! Control the LEDs in Standalone mode or connect to a host and control the tree from one of the many supported languages and devices. The 2 boards (A and B) slide into each other, turning this into a 3D-ish module!
We are including a USB cable. You only need to connect it to a computer or a phone charger! Everything you need to get started is at: holidaytree.duelink.com
This board ships preloaded with MicroBlocks firmware.
