Circuit Documentation

Summary

This circuit integrates an Arduino UNO microcontroller with various peripherals including an I2C LCD 16x2 Screen, multiple 2.2 inch Basic Flex Resistors, a buzzer, a set of 10k Ohm resistors, and an HC-05 Bluetooth Module. The Arduino UNO serves as the central processing unit, interfacing with the LCD screen via I2C communication and controlling a buzzer. The flex resistors are likely used as sensors, and the 10k Ohm resistors may serve as pull-up or pull-down resistors or for current limiting purposes. The HC-05 Bluetooth Module enables wireless communication, possibly for remote data monitoring or control.
