What is Arduino?

Arduino is an open-source electronics platform used to build interactive projects. It includes both hardware (a microcontroller board) and software (Arduino IDE).

The most common board is the Arduino Uno, which contains a microcontroller that can be programmed to control lights, motors, sensors, and other components.

You write code in the Arduino IDE using a simplified version of C++. Then you upload the code to the board using a USB cable.

The Arduino can:

• Read input from sensors
  
  

• Control LEDs and motors
  
  

• Display data
  
  

• Communicate with other devices
  
  

It has digital pins (on/off signals) and analog pins (variable signals).

Arduino is popular in education, robotics, automation, and DIY electronics because it is affordable and beginner-friendly.

In summary, Arduino is a programmable microcontroller platform used to create electronic projects and smart systems.
