Write a program that uses the analog input to control two LEDs as follows: ⋅ If the input voltage is in the interval [2, 3] volts both LEDs are off. ⋅ If the input voltage is in the interval [0, 2] volts, one LED is on and the other is off. ⋅ If the input voltage is less than 0 volts or greater than 3 volts, both LEDs are on. What is the purpose of this program?
