How does a microcontroller work?
A microcontroller operates by executing a program stored in its memory. The basic functioning involves:
- Input: It receives data from sensors or user inputs through its I/O pins.
- Processing: The central processing unit (CPU) processes the input data according to the programmed instructions.
- Output: Based on the processed information, it sends commands to control outputs, such as motors, lights, or displays.
- Feedback Loop: It can continually monitor inputs, process data, and adjust outputs, creating a feedback loop for dynamic control.
We hope this explanation helped you learn about microcontrollers, their uses, and how they work in various applications.
