Blinking L LED (No Blink example) [solved]

Alright, I have never worked with resistors because I understand only the smallest thing about them, which is that they control electricity power, but I never have used them, but ok I will do research about the INPUT_PULLUP and get back to you once I will add that into my code, thanks for responding, also I will change up the code's "if" statement. Again, thanks.
