Morse Code Alphabets
Morse Code
Morse code is a process of transmitting reports and information through
the use of lights, tones or clicks that can be understandable. Morse
code was invented by Samuel Finley Breese Morse in 1849. The codes are
usually written in dots dashes and spaces which represents the letter on
the alphabet.
Make it work
You can create your own Morse code tappers to send and receive secret messages.
You will need
- 2 pieces of wood 2 batteries
- 2 bulbs and bulb holders wire
- 2 strips of copper
- paper clips
- 2 slices of cork
- glue
- screws hacksaw (and an adult to use it)
International Morse code
Morse codes are made up of symbols such as
dots, dashes, and spaces. A dot is transmitted by pressing and instantly
releasing the transmitter key. To send a dash, hold the key down twice
as long as you did for the dot. A space between the letters is the same
length as a dot, and a space between words is the same length as a dash.
Procedures:
- Screw the bulb into position and glue the batteries into the
board.
- Ask an adult to saw the copper strips into four pieces two long
and two short.
- Glue one short piece to the end of each board opposite the bulb
holder.
- Glue a slice of cork onto each transmitter key and wire up the
keys. When you press the cork, the long
copper strip should touch the short one underneath and both bulbs
will light.
