Embedded Systems & IoT
Program the hardware inside everything.
Embedded engineers write software that runs on microcontrollers in devices.
What the work looks like
Writing firmware in C, debugging with oscilloscopes, integrating sensors, testing hardware.

Reality check
Students like: Blinking an LED you control at register level.
Students dislike: Bugs that only appear on real hardware.
Hardest part: Memory and timing constraints.
Common myth: Arduino projects are a start, not the job.
