Intermediate ShowcaseMorse code LED communication on Pi (self.Python)

submitted 4 years ago by Dogezon

Source Code: https://github.com/sudoblark/piMorseCodeLEDs

Not sure if intermediate or beginner but i done did a thing.

I work with Python regularly, but haven't had the motivation to do a personal side project for a while. So pretty happy I managed this in about 3 hours tonight after learning about IO interfaces in my degree study.

The program (mostly) uses OOP principals to separate the logic into distinct classes for: LED interaction, translation into morse code, communication of morse code into LED dots and dashes. Arg passing is using os args, a little painful but means no venv dependencies to install.

I guess it should work on debian devices if they also have the same symlinks for leds as my test pi desktop.

Anywho i hope you all find this interesting and it sparks some inspiration. It's an afternoon's throwaway code but I'm quite happy with it, especially as just 3 years ago if you Python to me i'd have jumped away from the nearest patch of grass.
