Summary of the Circuit

This circuit is designed around an Arduino UNO microcontroller and includes various peripherals such as two HC-SR04 ultrasonic sensors, multiple LEDs (both red and green), and two buzzers. The circuit is likely intended for distance measurement with audible and visual indicators. The Arduino UNO provides power to the sensors and controls the LEDs and buzzers based on the sensor inputs. However, no embedded code is provided, indicating that the functionality is not yet implemented or is not available.

Documented Code

No code has been provided for the microcontroller. The expected functionality would include initializing the I/O pins, reading distance measurements from the HC-SR04 sensors, and then activating the LEDs and buzzers based on predefined distance thresholds. Without the code, the specific behavior of the circuit cannot be documented.
