Need Help, Baby- O programing

Hello.

You might try reviewing Arduino’s Blink Without Delay example, which uses millis() to blink an LED. If you try that and are still not able to get your system to work, you could post the simplest version of your code that demonstrates the problem, and I might be able to help you figure it out.
