Microcontrollers in Arduino Embedded Systems

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
