@nprofile1q... The cool thing about microcontrollers is, they have very little RAM, so the current conditions barely affect them ๐
The microcontroller development board I got is about 2~3EUR on the usual Chinese imports websites. I also got a 15EUR bag of assorted modules to play around with, then ~10EUR more in wires and breadboards.
(Prices converted from BRL, your mileage may vary)
These development boards are programmed and powered over USB, and can power a reasonable amount of components off it, you don't need any fancy tools.
You might even scrounge some stuff for cheaper if you look in the used market depending where you live, some people buy some kits then never do anything with it.
As far as hobbies go it doesn't seem like it's very expensive to enter? Please correct me, I probably need a reality check. It sure can get expensive if you wanna do advanced stuff and need to buy a logic analyzer or somesuch, but there's a looong runway before that is even close to necessary.
