The Arduino programming language is based on C/C++, which means that it shares many of the same syntax and structures as these languages. However, the Arduino programming language has some specific functions and libraries that are unique to the platform.
Here are some key features of the Arduino programming language:
1. Setup and Loop functions: Every Arduino sketch (program) has two main functions: setup and loop. The setup function is executed once when the board is powered on or reset, and is used to initialize variables, set pin modes, and configure any necessary libraries. The loop function is executed repeatedly after setup, and is used to perform the main program logic.
2. Pin manipulation: Arduino boards have a range of digital and analog input/output pins that can be used to connect and control various components such as LEDs, motors, and sensors. The pinMode(), digitalWrite(), and analogWrite() functions are used to set the pin mode (input or output) and to write digital or analog values to the pins.
3. Serial communication: Arduino boards can communicate with computers and other devices using serial communication over USB or other interfaces. The Serial.begin() function is used to initialize the serial communication, and the Serial.print() and Serial.read() functions are used to send and receive data.
4. Libraries: The Arduino programming language includes a range of libraries that provide pre-written code for common tasks, such as controlling LCD displays, reading sensors, and communicating with other devices. These libraries can be included in a sketch using the #include directive.
5. Interrupts: Arduino boards can use interrupts to respond to external events, such as a button press or a sensor reading. The attachInterrupt() function is used to set up an interrupt, and the ISR (Interrupt Service Routine) function is executed when the interrupt is triggered.
Overall, the Arduino programming language provides a simple and accessible way to program microcontroller boards, while still offering the flexibility and power of C/C++. The use of specific functions and libraries tailored to the Arduino platform makes it easy for beginners to get started with programming and electronics, while also allowing experienced programmers to create more complex projects.
