No-one ever uses the microcontrollers they buy and they certainly don’t finish projects - that would be breaking the laws of nature.
No, we buy these devices because we like the idea of making a project with them and enjoy the satisfaction that hitting the “buy” button gives.
When the item is delivered (only a 50/50 chance if you bought it from Aliexpress), put it safely in a drawer and think happily about how your project would work if you ever did it. Which you won’t. You will feel an ongoing warm glow from your accumulated collection of microcontrollers and oddball electronics that you’ve bought and you’ll marvel at how little it cost to buy so much computing power that you’ll never use.
You watch makers on YouTube to vicariously see projects finished. Then you get inspired and buy. Then you put it in a drawer. Then you go back to watching makers on YouTube. It’s the cycle of maker life.
