controlling LCD

hi there im doing a project for collage and I have to put in the LCD into it. the LCD will be used to count the time for a counter. so basically there will be a timer for 5 second and I hope to have the LCD count down from 5 to 0, how would I do this? would any one have any basic code that I could inset or even a basic LCD circuit and coad that I can do to learn from. thanks

What have you found on google?

i found a few difrent ones but i cant seam to get them working. im at this one at the moment but i cant seam to get it working

“Can’t get it working” is not giving us much to go on. You are going to have to type out the details. Plus, you need to post the code you are working with in code tags.
