Made this LED tree with a bunch of single-colored LEDs and ping-pong balls for a class I took last quarter.
The tree contains many small clusters of LEDs which can be controlled using a Raspberry Pi. I haven’t fiddled around much with the programming part, but I plan to map weather data on the tree.
I am also thinking of making it responsive to different sensors like sound sensors and proximity sensor. Will see where I go this tree 🙂
