Using a Pi Pico to Convert Keyboard Input to Morse Code -- Episode 573

Ever fancied sending a message via Morse code, but the process of working out the dots and dashes seems daunting? Then why not make a keyboard that will convert the text you type into Morse code, in an audible and visual form!

    If you were able to decode that with out computer aid, you deserve a prize! I cheated and used: https://morsecode.world/international/translator.html lol

    Thank you! Made me realise, I didn't add punctuation in my code, I'll add that when I get a chance.

    Interesting, I've been trying to think of a project to incorporate LORA as I've not done much with it before

    Morse code decoding can get a bit tricky since all timings are variables and they all have a significant tolerance. It would likely make a good ML or AI application, although it can be done with just rules, ratios and tolerances.

    I had never heard of spudgers, although now that I looked it up, I need some. (tire irons for plastic boxes) Relaxed

    Nice project Katie.

    I first learned morse code over fifty years ago when I was in the radio club in High School.

    I ran into it again when I was the IVV for the Integrated Communications Navigation Identification Avionics project.

    They created this really cool decode logic to convert the morse code into text from the instrumented landing beacons.

    I hope you use the device to get a taste of radio communication.

    You might want to look at RTTY (radio teletype) as well then. Baudot-Murray code over the radio.

    I recall in the 80's a student doing this on a ZX81 with his amateur radio.

    For a STEM activity you could perhaps try to use LORA to communicate over longer distances.

    Also guitar plectrums, so it doesn't close back down whilst trying to get the next clip open.

    Yes, I like spudgers. I've got a few various sized ones, nothing big enough for car panels though. For some reason I thought I'd try just using my fingers for this and it opened up without too much difficulty, so I didn't bother getting the box down

    Hadn't thought of that, that would be an interesting project collaboration/meetup
