In this project, we are building an electronic piano that can be played utilizing coke cans as user inputs. Here, the Coca-Cola cans are serving as capacitive switches. The capacitor, which has two basic characteristics, charge and discharge, functions as a switch state and a change in the dielectric leads to a change in charge, which produces a change in the analog voltage. Thus, based on these analog voltages, we may generate various piano tones for various switches in accordance with the outcomes of the music player and switch states. Following this essential operating concept, we use a human touch circuit via trig and input electric fields to build the capacitor. Following the development of the input sensor, a piano tone generator based on a timer and PWM frequency generator is used to generate the output tone. Then, we use an SD-Card to store the recordings that can be played back using a reader, convert the SD format to digital, and then again convert digital to analog using a DAC. As a result, we may create music players and piano tones based on switching states and dielectric variation, respectively.
