    • Open-source hardware encourages collaboration
    • It allows for users to read the design files, make improvement, and redistribute these improvements
    • Arduino design files, schematics, and software are available for free use, modification, and redistribution

    Arduino Library

    • The Arduino library provides a simplified set of functions for programming Arduino interface boards
    • The Arduino library uses C++
    • The majority of Arduino code is written in C, including:
      • Syntax
      • Structure
      • Operators
      • Control statements
      • Functions
    • Key Arduino library functions:
      • pinMode()
      • digitalWrite()
      • delay()

    Arduino Programming

    • Arduino programming uses a top-down structural programming approach, executing code in order from top to bottom
    • Arduino programs must have a setup() and loop() function
    • The setup() function is used to initialize variables or configure hardware
    • The loop() function runs continuously, executing instructions repeatedly

    Getting Started with Arduino

    • A basic Arduino setup includes a microcontroller and a computer.
    • The Arduino microcontroller can be powered via USB from the computer for many projects
    • The Arduino code can be uploaded to the microcontroller via the USB port

    Comments in Arduino Code

    • Arduino comments begin with // and are ignored by the compiler
    • Comments are used to provide documentation
    • Comments are useful for:
      • Providing project information
      • Describing the purpose of variables
      • Explaining function requirements
      • Documenting code changes
    • Comments do not affect the size of the program on the microcontroller

    Troubleshooting Arduino Errors

    • Check that the Arduino board is powered on and connected to the computer
    • Ensure that the correct serial port and board type are selected under the Tools menu
    • Consult with the Arduino reseller for more serious hardware errors
