I must Create a program and interface to turn on three lights in a forwards chase. Each light should stay on for approximately 1 second. The lights should be continuously on a forward chase until '0' is pressed. Any help would be helpful. Thanks!!
Any help would be helpful.
With what? Defining what "a forward chase" means?
Turning pins on and off is trivial. Reading serial input is trivial.
What have you tried?
Google has MANY examples of "arduino LED chase"
Have you looked at any of them?
Have you connected LEDs to your arduino following instructions on any of the blink tutorials?
