Get one of those learning kits that come with most of SBC/MCUs (like raspberry pi or ESP32) which have a lot of random stuff (like LEDs, motors etc.) that you can hook up to the pins and write C programs to control them. Learn the different protocols that are used to talk to other devices, like i2c, uart, spi etc. and then buy some hardware that you can talk to via this protocol. Like a sensor, a gps module or an IMU or EEPROM.
It's conceptually pretty similar to how computers and device drivers do it. There is some communication protocol and you can write or read some values over it to use any device. It's just way easier to start small and build up experience from there.
Oh I see, well I've done some circuitry so that helps I guess. Thanks for clarifying, it's just a bit intimidating but exciting field, I'm starting rn with some arduinos and basic sensors then. Also from a job perspective, do you see viable to pursue low-level development remote job? I have worked with git, and I'm working to improve my github profile so that I can offer more while polishing my skills, but I personally haven't seen much remote job offers for low-level junior dev, sadly in my country it is not common either so that's why I'm interested in a remote one.
I'm not actually working in the field, so I can't give you any advice there.
I studied a related topic, before pivoting into a different career. And I do hardware and drivers stuff in my free time sometimes for some fun projects.
