Step 2:Explain the code:

//Read potentiometer's simulation value, and assign values to the smiling face of the x coordinate values

 void draw() {
   sensorValue = arduino.analogRead(potPin); //Reading the value of the potentiometer
   background(255);
   image(face,sensorValue,80);
 }

Step 3: Compile the code and download it.

Step 4: After running, a smile face will display on the left side, rotate the potentiometer and then observe the smile face's change.

Result

The smiling face on the screen will move around with the potentiometer's rotation, as follows:
