HELP PLEASE!
i'm new to all of this and I'm using the manual I got when I bought the arduino yesterday and have copied the code exactly but it comes up with this error:
Arduino: 1.6.5 (Mac OS X), Board: "Arduino/Genuino Uno"
LED_blinks.ino: In function 'void setup()':
LED_blinks:12: error: 'ledPin' was not declared in this scope
LED_blinks.ino: In function 'void loop()':
LED_blinks:18: error: 'ledPin' was not declared in this scope
'ledPin' was not declared in this scope
This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.
HOW DO I SOLVE IT? thank you
