7 segment display

[another guy]

hey guys i know this sounds simple but how do you display a letter on a 7 segment display.when it reaches a top sensor it should display H and when it reaches a bottom sensor it should display L.ANY help out there?

This diagram here; http://www.cs.binghamton.edu/~steflik/cs423/7segment/pinouts.jpg
should tell you what you need.

I.e. to display an H, put voltage on pins 10, 8, 5, 2 and 9 (segments b, c, e, f, g)

And remember to include the resistors!

It's pretty simple, why don't you have a stab at it, then when you're stuck post what you've got and we'll tell you how to fix it. Rather than have us do it for you, which means you learn nothing.

Take a look at this thread. It may give you some ideas on how it can be done.
