RTOS vs Arduino Super Loop

When you build firmware for a microcontroller, you usually end up choosing between two patterns: the simple Arduino-style loop() or a full RTOS-based design. Both can work well, but they solve different problems.

The Arduino super loop is easy to understand: run setup once, then repeatedly execute the same code in a loop. An RTOS, on the other hand, gives you multiple tasks that can run concurrently, wake up on timers, wait for events, and share the CPU in a controlled way.
