···· · ·−·· ·−−·
"Help" in Morse code is ···· · ·−·· ·−−·.

"Help" takes 37 units, about 2.2 seconds at a speed of 20 words per minute.

Did you know?
- The code used today is International Morse Code, based on a version Friedrich Gerke made for German telegraph lines in 1848. It differs from the original American code in many letters.
- Alfred Vail, who worked with Samuel Morse, gave the shortest signals to the most common letters. That is why E, the most frequent letter in English, is a single dot.
