Develop a VI dial control that goes from $0$ to $2,$ with three LED displays: one green, one yellow, and one red. Have the VI turn the LED green when the dial is on $0,$ yellow when the dial is on $1,$ and red when the dial is on $2.$

Hint: Use the Compound Arithmetic function found on the Programming$>>$Numeric palette to add the five inputs together.
