Modify the program that will display a status bar (LED displays to act as status

Modify the existing code that will display a status bar (LED displays to act as status bar) if the frequeny increases the status bar increases and vice versa. Frequency starts with 100.

This feels like the description of a homework assignment.... where is your attempt?
