scope of variables in Arduino C

Q&A Forum › Category: Arduino › scope of variables in Arduino C

I know that variables defined at the top of a sketch are globally accessible, and those defined inside the loop() function are only accessible in that function, and variables defined inside a for loop are only accessible within that for loop. but what about variables defined inside the setup() section? Are they only available within the setup section?

Hi Stewart, variables defined within the setup() are only available in the setup() function. The setup() is just like any other function, so the same rules apply. I hope this helps!
