What Is Arduino and What Is It Used For?
Arduino is a small programmable electronics board used to build interactive projects that can sense and control things in the real world. It combines hardware (the board) and software (Arduino IDE), making it easy for beginners and professionals to create electronics projects without deep engineering knowledge.
At its core, Arduino reads inputs (like buttons, sensors, or temperature) and turns them into outputs (like lights, motors, displays, or alarms) based on the code you upload.
What Makes Arduino Popular?
Arduino is widely used because it is:
- Beginner-friendly – easy to learn, even with no electronics background
- Affordable – low-cost boards and components
- Open-source – huge global community and support
- Flexible – works for simple and advanced projects
