How does the Arduino IDE know whether you want to simply assign a value to a variable vs assigning a name to an Arduino pin?
I want to do two things.
-Assign digital pin 5 to redLed
-Assign the value 5 to (global) myVariable1
int redLed = 5;
int myVariable1 = 5;
Or, to put it another way, how do I differentiate between the two requirements?
Is it because the system only looks for pin assignments in the sketch area before that comes before "Void Setup()"
I have spent several hours reading tutorials and watching videos, trying to get to the bottom of this.
The people just stuff up at the top and it seems to work.
Sorry that I coulldn't figure this out on my own. I never did come up with a search string that would get me to what I am trying to ask.
