Circuit Documentation

Summary

This circuit consists of an ESP32 microcontroller, a 16-channel analog multiplexer, and multiple piezo sensors. The piezo sensors are connected to the multiplexer, which in turn is controlled by the ESP32. The purpose of this circuit is to read analog signals from multiple piezo sensors using a single analog input pin on the ESP32.
