A bit of inexpensive fun?

A 'talking' Morse code decoder

filename: aht3MorseTalker.htm

Nothing fancy here... just four things working together. Two will be things many readers already have. The other two are not expensive.

Imagine a "thing" with a momentary switch at one end... a simple 'doorbell' type switch would do. A Morse code key would be perfect. And at the other end a speaker.

If some one tapped the switch "dah-dah-dah" (pause) "dit-dit-dit" (pause) "dah-dah-dah", the "thing" would 'say' "S" "O" "S" !

Cool? Of course cool! (If you are a Right Thinking Person!)

And it wouldn't be expensive. It wouldn't be hard to create.

You'd need...

Arduino, and means of programming it. (I assume you have.)
Simple powered speakers... the sort you use to listen to YouTube audio. $15? If you don't have!
A Big Buddy Talker. (Or even the earlier Little Buddy Talker). $20? $30?
A Bonet ATtiny Morse reader. $20?

You'll have to learn about the Talker and the Bonet Morse reader. Both EASY. Details at the pages cited.

The Bonet Morse reader accepts the input from the momentary switch, and creates a serial data stream with the ASCII for what was tapped on the Morse key. Typically, it drives a read- it- with- your- eyes display, sometimes "through" an Arduino. (The Arduino IDE makes turning the serial stream into figures- on- a- screen easy. You just use the serial monitor. You could still have this with a SPEAKING Morse reader.)

The Arduino would have to look up the number for whatever letter needs to be "said" by the Big Buddy Talker. (The Talker says words, and you tell it what word you want by sending it a numbers. (Besides words like "start", "stop", "five", etc... the Talker also can "say" "A", "B", "C"... etc... it treats the names of the letters as "words".)

That's it! The rest, e.g. the simple little program for the Arduino, the hooking up, etc, is VERY EASY. I hope I don't have to explain? It is, really. If you will buy the bits, I will help you connect them... if you need it! Contact details below.

Site Map What's New Search
The search engine is not intelligent. It merely seeks the words you specify. It will not do anything sensible with "What does the 'could not compile' error mean?" It will just return references to pages with "what", "does", "could", "not".... etc.

In addition to the tutorials for which this page serves as Table of Contents, I have other sites with material you might find useful.....

Sequenced set of tutorials on Arduino programming and electronics interfacing.

If you visit 1&1's site from here, it helps me. They host my website, and I wouldn't put this link up for them if I wasn't happy with their service.

Ad from page's editor: Yes.. I do enjoy compiling these things for you... hope they are helpful. However.. this doesn't pay my bills!!! If you find this stuff useful, (and you run an MS-DOS or Windows PC) please visit my freeware and shareware page, download something, and circulate it for me? Links on your page to this page would also be appreciated!

Why does this page cause a script to run? Because of the Google panels, and the code for the search button. Why do I mention the script? Be sure you know all you need to about spyware.
