Scrolling Underscore on 16x2 LCD

Post by adafruit_newbie »

Can I include a scrolling underscore (_) that will be controlled by the left/right/up/down buttons on the LCD shield? I want to display a line of numbers, 0-9 and have the user select one using the different buttons. The only thing that would change is the position of the underscore, and the code would keep track of where the underscore is at all times.

Additionally, does anyone have a better idea (requiring less code than this would) to have a user input a 3 digit number from 30-200 using the LCD shield and up, down, left, right, select buttons?

Thanks!
