This project was made for interactive exhibit in Delhi. The concept is people would have a screen in front of them and instruction will be shown on the screen, so they would play the rhythm and a video will be played on the screen.
Each piano key is made from two card board cut-outs with Al foil one side, and they are separated by a thin layer of polystyrene. When the switch is press, it is read by arduino and data is sent serially to python script which plays the sound, and displays the instructions and plays the video. I’m waiting for images and videos from the exhibit, I’ll upload as soon as I get it.
Here is the cardboard cut outs, crafts is a difficult thing to do.
Huge help from my niece.
