Circuit Documentation
Summary
This circuit integrates an Arduino UNO microcontroller with an HC-SR04 Ultrasonic Sensor. The Arduino UNO is responsible for controlling the sensor and processing the distance measurements. The HC-SR04 sensor is used to measure distances by emitting ultrasonic waves and measuring the time taken for the echo to return. The circuit is powered by the Arduino UNO's 5V output, and the sensor's trigger and echo signals are connected to digital pins on the Arduino for control and data acquisition.
