Jellyfish/Cake

90 Replies

Yerang Choi and I worked on creating a piece with LEDs that would respond to noise/sound.

We used a small plastic piece in which we punched holes through with thumbtacks. After this we stuck in our LEDs that we had soldered to wires and resistors. There are a total of ten LEDs. Surrounding the plastic so as to hide the inside organs of our piece is tin foil. The piece resembles a jellyfish or a cake. We took inspiration from some videos on YouTube:

And the code!!!!!
