Embedded C Programming Practice Exam

Embedded C Programming Practice Exam

Embedded C Programming is the use of the C language to write software for small electronic devices, often called embedded systems. These are the "brains" inside everyday gadgets like washing machines, microwaves, remote controls, or even cars. Instead of running on a regular computer, the code is written to control a microcontroller (a tiny computer chip) that directly interacts with hardware.
It allows engineers to tell machines exactly what to do—turn on a motor, blink an LED, measure temperature, or control sensors. Embedded C is simple yet powerful because it combines the efficiency of the C language with direct hardware control. This makes it one of the most widely used languages for electronics and IoT (Internet of Things) devices.
