Is there a single language I could learn that would allow me to write code for iOS, Linux, and possibly even micro controllers such as the Arduino?

I am currently a mechanical engineer with a little bit of basic electronics knowledge, and have spent many years running various flavors of Linux and writing small bash scripts to automate various tasks. So I'm not exactly starting from 0 when it comes to learning programming...but still only at maybe a 1 out of 100, lol.   


I am equally interested in coding for hardware, micro controllers, sensors, etc, think IOT devices as well as apps for iPhone, iPad, MacOS, and Linux. But I dont want to end up overwhelming myself by trying to learn multiple languages at once. So is there any 1 language that can be used on all these platforms?

C or C++ is going to be essentially you're only option. Microcontrollers don't usually have support for other languages.

Unfortunately the Apple ecosystem is particularly locked down, to write apps for their products you *have* to use an Apple computer and an Apple programming language (e.g. Swift) is strongly recommended. You can use C++ (using e.g. Qt) but it won't be the easiest experience.
