Working with the ultrasonic sensor, I learned how it works and how to measure distances using ultrasound. The project involves programming the Arduino board to read data from the sensor and control the buzzer. The created device can be used to measure distances in various contexts, such as avoiding

Programming to read the distance and control the buzzer is difficult. We had to understand how to use Arduino functions and libraries. It is important to properly connect the ultrasonic sensor and buzzer to the Arduino board. A wrong connection can lead to errors in operation.

If we had more time, we would have calibrated the ultrasonic sensor to obtain accurate measurements.
