I want a code where the LDR receives the signal from LASER and converts the morse code into original text and displays it into the 20*4 LED display?? If anyone has it please give it to me it would help me for my project??

[image] naveenjr: Does this do the same as i have mentioned or is it little bit different? Chances are you won't "find" code that does exactly what you want, at least not for free. So, you can either adapt existing code to your needs or pay someone to do your work for you.

The above code does not even run in arduino mega so it is hard

The above code does not even run in arduino mega I wonder what your mistake(s) might be.

[image] naveenjr: The above code does not even run in arduino mega so it is hard Correct it will not run by itself, it is only the "clever bit" that does the decoding. You have to feed it with the right data. Are you doing that?

[image] naveenjr: Does this do the same as i have mentioned or is it little bit different? If anyone has the code to connect your specific LASER, LDR, and 20*4 display to your Arduino, it would probably be a person who has your specific LASER, LDR, 20*4 display, and Arduino.

A mores code decoder was the first embedded project I did, back in 1976. But it was written in 2650 machine code, note not even assembler. What would surprise me is if a laser on an LDR would produce a signal fast and clear enough. An LDR has a large surface area compared to a laser spot so it woul…

a simple morse decoder could use a structure such as // structure to hold character and its morse code struct morse { char letter; char code[6]; }; // array defining charracters and equivalent codes struct morse morse_code[]= { {'A' , ".-"}, …

[image] horace: add statements to read a string then and you have explained the hurdle... Morse comes in as dots/dits and dashes/dahs. There is no carriage return and the speed is clocked by a human, not consistent. So, were one receiving ASCII from the serial port, your idea is grand. Oth…
