Microcontrollers in Arduino Embedded Systems

Study Notes

Microcontrollers in Arduino Embedded Systems

A microcontroller (MCU) is the brain of an Arduino board, responsible for executing instructions and controlling the system.
Arduino boards use Atmel AVR microcontrollers, specifically the ATmega328P or ATmega2560.
Key features of microcontrollers in Arduino:
- Low power consumption
- Small size
- High processing speed
- Integrated memory (flash, RAM, and EEPROM)
- Input/Output (I/O) peripherals (e.g., digital and analog pins)

Programming Languages for Arduino Embedded Systems

Arduino uses a modified version of the C programming language, often referred to as Arduino Language or Arduino C.
Key features of the Arduino programming language:
- Simplified syntax and structure
- Built-in functions for I/O operations, timing, and math
- Support for object-oriented programming (OOP) concepts
Other programming languages can be used with Arduino, including:
- C++ (with additional libraries and frameworks)
- Python (using libraries like Pyserial or Arduino-Python)
- Java (using libraries like Arduino-Java)
- Scratch (a visual programming language for beginners)

Programming Environments for Arduino

The Arduino Integrated Development Environment (IDE) is the official programming environment for Arduino.
Features of the Arduino IDE:
- Code editor with syntax highlighting and auto-completion
- Compiler and uploader for flashing code to the board
- Serial monitor for debugging and communication
- Library manager for easily installing and managing libraries
Other programming environments and tools can be used with Arduino, including:
- Visual Studio Code with Arduino extensions
- PlatformIO
- Eclipse with Arduino plugins
