How to identify block separately GUI

I want to identify or glow one block at a time respect to the input value. ex., if the input is numbers, if input = 3 glow third block, if input is 6 glow sixth block like vice.

What is the input value? What should what appear and how? Is this an image, 6 buttons, a table object, an Excel file or printed on paper?

this is a sample GUI with 6 blocks. input values are 1 to 6 , one input per time. when one number input to the GUI relevant block must glow. think as six LEDs.
