1. Using servo knob on Arduino IDE, verify that you can controlthe orientation of the servo horn by rotating the knob of thepot.
2. Modify the Servo_Knob sketch from 1, so that you can print tothe monitor both the raw pot voltage and its scaled value.Determine what the maximum and minimum values are for the potvoltage when you turn the knob to its extreme CW and CCWdirections.
3. Change the 1023 argument value in the map() function tocorrespond with the maximum pot voltage value that you determinedin the previous step.
4. Write a program that will light up one of the four red‘gumdrop’
