[SOLVED] digitalWrite or pinMode not functioning inside .cpp file

Aaaaah I must've done that when I tried making stuff "const" to conserve space and ran into compiler errors. Good eye, thank you!

Follow-up, if you could be so kind: if I wanted to make a variable ("_ledPinGreen") be const within the class, would I declare it in the constructor? Or would this typically just be forgone in favor of simply declaring it normally?
