Not sure about the duolingo coding, but stardust is earnt when you ship your project, i think. The resources page has a guide when you think it’s time to ship and a good breakdown of what shipping means and how stardust is awarded :]

thanks!

You can submit your project and can earn stardust as this formula stated :- number of coding hour X the multiplier you get by the rating of your project (known from a frnd) and as far as learning you can start learning coding with CS50 X it is a Harvard free course am doing it and it is pretty much helpful

you should also do free coding camp aside form CS50 do further deepen your knowledge afterwards start doign some leetcode when you got the basics down an build some projects. like arduino or esp32 are quite easy with c
