Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, a pushbutton, and an LCD I2C display. The Arduino UNO serves as the central processing unit, controlling the input from the pushbutton and outputting data to the LCD display. The pushbutton is used as an input device, and the LCD display is an output device that shows information to the user. The circuit is designed to read the state of the pushbutton and display relevant information on the LCD screen.
