    This code doesn’t compile, it contains an error and an incorrect comment:

    The error:
    – It define LEDPin but then refers to ledPin. Replace one or the other to agree with the other one.
    The Incorrect comment:
    – The “delay(25)” does not pause for two seconds. The parameter to delay() is in milliseconds. it should be delay(2000)

    None of this is really hard to fix but you may want to correct the code.
    Thank you
