Summary of the Circuit

This circuit is designed around an Arduino UNO microcontroller and includes two HC-SR04 ultrasonic sensors and a pushbutton. The Arduino UNO is used to interface with the sensors and the pushbutton to perform specific tasks, which are defined in the embedded code. The HC-SR04 sensors are used for distance measurement, and the pushbutton serves as a user input device. The circuit is powered by the Arduino UNO's 5V output, and the ground connections are shared among all components.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
