  1)Write a program that reads the 10 slider switches, and: a. Displays their value on the 10 Green LEDs b. Convert the values read from the 10 slider switches to hexadecimal and display the result on the appropriate number of 7-segment displays. The decimal point should remain off. 2) Use the Example program as a template (no rotation required in this exercise) 3) Loop the program continually so new choices can be entered.  1)Write a program that reads the 10 slider switches, and: a.
