Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino UNO microcontroller, multiple Force Sensitive Resistors (FSRs), resistors, and an MLX90614 infrared temperature sensor. The circuit is designed to read analog signals from the FSRs and the temperature sensor, process them using the Arduino, and potentially perform actions based on the readings.
