HOW IT WAS MADE:

I created the casing by turning High Density gray foam on the lathe into a pot plant shape, and hollowed it out using several drill bits. I cut and etched the pattern on the leaves with the laser cutter, and bent it using a heat gun. I then spray painted the pot part with brown spray and colored the leaves by spraying underneath it (on the smooth, not frosted side) with green spray. The 'lid' part is made from a laser cut piece of frosted acrylic also, and the stem is a brass tube, band-sawed to length and then secured in place through cutting slits and folding them over after force-fitting it into the laser cut hole in the acrylic lid.

HOW IT WORKS:

The small microphone sensor that is connected to the arduino inside the pot plant takes in amplitude inputs, and through my code, I got it to convert the amplitude inputs into frequency. What the code then does is that it will move the servo so that it is at 180 for 10 seconds, whenever it detects high frequency noises (>2000Hz) that are over a certain amplitude (>80). The servo arm is connected to the leaves by strings, and once it moves from its original position (0) to 180, it makes the string go from taut to slack, and therefore makes the leaves drop from the stem. When that certain range of sounds is not detected anymore, it goes back to its original position (0) again.
