Answer:
Morse code consists of dots and dashes, but it's not really binary, which consists only of zeros and ones. A telegraph key is pressed very quickly for a dot or dit, a bit longer for a dash or dah. You need to add a pause between letters/numbers.
The letter N is dash dot; the letter C is dash dot dash dot. If you want to send two N's in a row you need a pause, i.e. dash dot <pause> dash dot. Typically you'd use a short pause between each letter in a word and a longer pause between each word.
