Is morse code the same as braille?
No. Morse is a signal measured in time, one tone switched on and off in two lengths, and it can travel as sound, light, vibration or touch. Braille is a shape read by touch: a cell three dots high and two dots wide, where which dots are raised, not how long anything lasts, carries the letter.

The flashlight needs camera access. Nothing is recorded or sent.
The word braille sent in morse, which is where the two systems differ most: this takes time to arrive, while a braille cell is there all at once.
Time against space
The clearest way to see the difference is to ask where the information sits.
In morse, it sits in time. ITU-R M.1677-1 allows two lengths of signal, a dit of one unit and a dah of three, and sets the gaps at one, three and seven units. A character does not exist at any single moment; it has to be waited out. Press Play above and the word takes several seconds to arrive.
In braille, it sits in space. The Braille Authority of North America describes the cell as three dots high and two dots wide, and a letter is whichever of those six positions are raised. Nothing is timed. The whole character is under a fingertip at once, and a reader moves along the line as fast as they can feel.
Different problems, different shapes
Each system took the shape its problem demanded.
Morse had to travel down a wire, and later through the air, where the only thing a receiver could detect reliably was whether a signal was present. Two lengths and a clock were all that was available, so the code was built from them.
Braille had to be read by a finger, which can feel a small pattern instantly but cannot follow a moving one. A compact fixed shape is exactly right for that, and a timed one would be useless.
What they do have in common
Both replace printed letters with something a different sense can take in, and both were designed so that a single person with no equipment can use them. Both also turn out to be good accessibility tools for reasons their inventors did not plan: morse now appears as a keyboard layout for people who can operate only one or two switches, because two signal lengths are all a switch has to tell apart.

Questions people ask next
What is the difference between morse code and braille?
Morse spreads a letter out in time and braille spreads it out in space. A morse character is a sequence of short and long signals; a braille character is a fixed pattern of raised dots you feel all at once.
How many dots are in braille?
Six in a standard cell, three dots high and two dots wide. Morse has no fixed number: a character runs from one mark to five or six.
Do morse code and braille use the same letters?
They cover the same alphabet but with unrelated patterns. Knowing one gives you nothing towards reading the other.
Can blind people use morse code?
Yes, and it needs no sight at all, since it arrives as sound or as vibration. Android's Gboard also offers a morse keyboard as an accessibility input method.
Can you feel morse code?
Yes. Vibration is the same signal delivered by touch, and our SOS page will vibrate an Android phone in time with each mark.
