I'd recommend you look into the Raspberry Pi, Arduino, or micro:bit - each offer a great introduction to physical computing with huge libraries of online content to dive into. https://www.raspberrypi.org/ https://www.raspberrypi.org/ <-- Basically a pocket sized computer which can run a full Linux stack and exposes a heap of useful IO options. https://www.arduino.cc/ https://www.arduino.cc/ <-- More akin to embedded systems - traditionally very low powered micro-controllers programmed in C. https://microbit.org/ https://microbit.org/ <-- Designed specifically for education and provides a number of high level abstractions for development including visual programming languages and MicroPython. As well as these there is a huge range of other options targeting different niches such as Javascript, Internet of Things, ultra low-power systems, etc. It really depends what you're interested in getting into. All of the platforms have starter kits, add-ons, and tutorials to get you going.
