In this project, students in groups of $2$ will create a system that utilizes an HC$-$SR$04$ Ultrasonic

Distance Sensor mounted on a servo motor. The servo motor will rotate the sensor clockwise with

user$-$defined incrementations entered via serial communication to cover its full range of motion.

At each angle, the sensor will measure the distance to an object. These distance measurements

will be stored in an array and averaged to determine the mean distance. The system will display

the average distance on an LCD. Additionally, buttons will be used to control the LCD, allowing

the user to switch between displaying the array of measurements, the increment size, and the

average distance. Furthermore, a button will enable the user to switch between displaying

distance measurements in centimeters and inches.

Software Development:

Write the Arduino code to wait for user input via serial communication to specify the

incrementation size for servo rotation.

Program the Arduino to control the servo motor's rotation with the user$-$defined

incrementations.

Read distance measurements from the HC$-$SR$04$ sensor at each angle of rotation.

Store the distance measurements in an array and calculate the average distance.

Implement functionality to switch between displaying the array of measurements $($one at

a time, using buttons to traverse the array$),$ the increment size, and the average distance

on the LCD.

Include logic to toggle between displaying distance measurements in centimeters and

inches based on user input.
