The twinkling glass
Description:
In this assignment I created the input/output coincidence on a wine glass. The experiment starts with an empty wine glass. While the glass is empty a very fast musical note plays along with fast blinking LED. You cannot figure out the song. As we pour water into the wine glass, the music slows down and you can hear the song more clearly. The tempo keeps going down as more water is poured.The LED inside the glass beats according to the tempo of the song.
The input provided is pouring of the water in the glass and the output is the slowing down of the song and the blinking of the LED is seen on the glass itself which shows input-output coincidence.
In this assigment I spent a lot of time in setting up of the wine glass, such that it could rest over FSR to measure the change in pressure when water is poured into it. I also has to cut the stem of the glass to fit the LED inside. I used multiple glasses on top of each other to create space to put the LED light.
