Minecraft wiki entry for Morse_code, associated text: This is the simplest of the three sections - all that needs to be achieved from this is something that can later be decoded into either a dot or a dash. To do this, you will need to make the signal for a dash longer than that of the signal for a dot. This can be achieved by using what has become known as 'Monostable Circuits'; which are easy to produce due to redstone repeaters. As repeaters can also be set on a delay, you can use this to increase the time take for the message to be sent through the wire.
