I'm a pretty proficient programmer. I have very little experience with microcontrollers or the hardware side of electronics in general, but I'd like to learn. I'm not even fully confident I understand how electricity works.
Does anyone have any resources they can recommend for diving into this? Or perhaps a kit, project, or list of things to buy to start tinkering around with?
did you try an internet search? It´s full of tinkering material and informations.
Now you may say: for sure, but there are too much results to choose from.
Yes. This is because you don´t give any requirements. Neither the internet search nor one of us knows what you are after, what you already know, which microcontrollers, which language, wich compilers, which kind of application....
