In C Arduino Please

Q4) Create an Arduino program that uses enum to create 3 states and does the following in

the states respectively:

State 1 - Starts a DC motor moving forward (this action should not stop)

State 2 - Waits for either your IR or Ultrasonic sensor to register an object within 10 centimeters.

State 3 - Turns the DC motor backwards for 1 second.

The program should run through the states in a repeating loop.
