Circuit Documentation

Summary of the Circuit

This circuit integrates a Raspberry Pi 5 with two Ultrasonic Sensors. The Raspberry Pi 5 serves as the central processing unit, providing power and GPIO connections to the Ultrasonic Sensors. The sensors are used to measure distances by emitting ultrasonic waves and measuring the time it takes for the echoes to return. The circuit is designed to operate with a 5V power supply from the Raspberry Pi 5, which is common for many low-power sensors and peripherals.

Documented Code

No code has been provided for the microcontrollers in the circuit. To fully utilize the circuit, embedded code for the Raspberry Pi 5 should be written to initialize and read the GPIO pins connected to the Ultrasonic Sensors' Trigger and Echo pins. The code should handle the timing of the signals and calculate the distance based on the time interval between sending the trigger signal and receiving the echo signal.
