Update: Sensors are working now
There are 8 sensors(copper tapes) on the sculpture. And they both can control the video (pattern) now.
I am going to connect them with my sculpture and hope it would looks pretty. A lot of wires and they might impact the beauty of sculpture. I just try my best to fix them….
Technical problem solved : Arduino/ Sensors/ Connected sensors to Processing
Thanks to Alex and Lauren for helping me figure it out.
