Post Body

So what I'm trying to do is have my code only activate an LED IF another LED is on. if the other LED is off, the LED won't change.

Here's my code. The buttonState is waiting for a button press. I need the "digitalWrite(go, HIGH); to only happen IF the LED(stby) is also HIGH.

buttonState = digitalRead(goin); if (buttonState == HIGH) { digitalWrite(go, HIGH); } else { digitalWrite(stby, LOW); }

I hope i'm making sense. I'm newer to this and i'm overall not sure how to explain. Let me know if more info is needed.
