The obvious way is to light an led behind a translucent panel with the letter painted on it. To display each letter is the second challenge.

Where the last choice stops is the result of the unique series of dots and dashes for that letter. (I pressed my keyboard keys to increase or decrease timeframes.)Įxample, if the first beep is a dot followed by a gap, you have letter E. Follow the right when a beep is a dash (greater than 12 mSec).Įnd a character when the gap is 25 mSec. (There are at most 5 steps or levels, assuming you make do with 32 characters.) Follow the left path when a beep is a dot (less than, say 12 milliSecond). The switching becomes complex, but it's one way to pursue proof of concept.Ĭreate an electronic branching structure based on whether a dot or a dash is encountered at each step. The output is a series of dots and dashes. Apply a network to a shift register (as an alternative, one or two 4017 decade counters). To make a gap apply a pull-down resistor. Otherwise you need to create artificial memory cells and artificial binary words.Įach character (dots and dashes) can be stored as a series of diode-resistor pull up networks. The job is easier with a computer of course. It successfully translated beeps into English text onscreen.
