Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s widely used by hobbyists, students, and engineers to build interactive electronic projects and prototypes.

What is Arduino? An Arduino board is a microcontroller that can be programmed to read inputs (like sensors) and control outputs (like LEDs, motors, and displays). Popular models include the Arduino Uno, Nano, and Mega.

Key components:

• Microcontroller (e.g., ATmega328P)
• Digital & analog pins
• USB connection for programming
• Power supply input

How to get started:

1. Install the Arduino IDE from the official website.
2. Connect your board via USB.
3. Write your first sketch (program) using C/C++ syntax.
4. Upload the code to the board and observe the results.

Example: Blink an LED

cppКопироватьРедактироватьvoid setup() {
  pinMode(13, OUTPUT);
}
void loop() {
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  delay(1000);
}

Project ideas:

• Temperature monitor
• Motion-activated light
• Line-following robot

Arduino is perfect for learning electronics and coding in a hands-on way. The community is vast, with tutorials, forums, and example projects available to help you get started quickly.
