Summary of the Circuit

This circuit incorporates two Arduino Nano microcontrollers, two HC-SR04 ultrasonic sensors (one being Wokwi compatible), a servo motor, and a buzzer. The primary function of this circuit appears to be distance measurement using the ultrasonic sensors, with the servo and buzzer likely providing some form of output or indication based on the distance measurements.
