Embedded systems are everywhere, yet learning them usually starts with a dense datasheet and a board that either works or silently doesn't. What happens inside the chip stays invisible — and that's exactly where most learners get stuck.
We wanted to make that inside visible. In EmbeddedPlayX, the microcontroller is a place you can explore: rooms for each peripheral, levers for each register bit, and a CPU you can watch fetch, decode, and execute the setup you just wrote.
Each mission drops you into a damaged spacecraft and asks you to bring one system back online. Fix the hardware, and you've learned how it works.
