Definition
Embedded systems are specialised computer systems designed to perform dedicated functions within larger mechanical or electrical systems. From washing machines and car ECUs to medical devices and industrial controllers, embedded systems are everywhere. They combine hardware (microcontrollers, sensors) with software (firmware, RTOS) to interact with the physical world.
Key Points
- Hardware: microcontrollers (ESP32, STM32, Arduino), sensors, actuators
- Software: C/C++ firmware, RTOS (FreeRTOS), device drivers
- Constrained environment: limited memory, processing power, and energy
- Convergence with IoT — embedded devices increasingly connect to the cloud

Frequently Asked Questions
C is the dominant language for embedded programming — it provides low-level hardware access with minimal overhead. C++ is used for more complex embedded systems. MicroPython and Rust are gaining traction for prototyping and safety-critical systems respectively. Arduino uses a simplified C++ that's great for learning and prototyping.
