Circuit Documentation
Summary
This circuit integrates two HC-SR04 Ultrasonic Sensors with an Arduino UNO microcontroller. The sensors are used to measure distances via ultrasonic waves. A 12V power supply is used to provide power to the circuit, and a XL4015 5A DC Buck Step-down converter is used to step down the voltage to a level suitable for the Arduino and the sensors. The Arduino UNO is programmed to interface with the sensors and potentially process the distance measurements.
