For my PComp final project, I experimented with Adafruit Neopixel and microphone amplifier module. My purpose of designing this project is for people who live under too much pressure and stress in their study or work. Inspired by a story of tree hole, I designed a tree hole box that can talk to. The Neopixel ring will light on or off depends on the voice volume. So when the users need to express some negative or positive thoughts, they can talk to the tree hole and get reactions from the heart.
