Arduino Programming Notebook

Study Notes

Arduino Programming Overview

The Arduino Programming Notebook is a reference guide for Arduino microcontroller programming, first published in August 2007, with a second edition in September 2008.
Content includes contributions from various developers like Paul Badger, Massimo Banzi, and others, providing a comprehensive resource for Arduino programming concepts.

Structure of Arduino Programs

Fundamental components include setup(), loop(), and user-defined functions.
Curly braces {} delineate the beginning and end of function and statement blocks, ensuring proper code structure.
Semicolons ; are mandatory for ending statements and separating elements such as loop parts.

Variables and Data Types

Variables must be declared before use, defining their type (e.g., int, long, float) and optionally initializing values.
Variable scope determines accessibility:
- Global variables (declared before setup()) are accessible throughout the program.
- Local variables (declared within functions or loops) are limited to the function scope, reducing potential errors.

Data Types Explained

Common data types:
- byte: 8-bit unsigned integer.
- int: 16-bit signed integer.
- long: 32-bit signed integer.
- float: 32-bit floating-point number.
Arrays can be used for grouped data storage.

Control Structures

Conditional statements include if, if...else, for, while, and do...while, directing program flow based on conditions.
Logical operators include AND (&&), OR (||), and NOT (!), allowing for complex condition evaluations.

Constants and Input/Output

Predefined constants exist to enhance code readability:
- TRUE/FALSE: Boolean values, where FALSE is 0 and TRUE is anything except zero.
- HIGH/LOW: States for digital pins; HIGH is typically 5V (ON), and LOW is 0V (OFF).
Digital and analog I/O functions include:
- pinMode(pin, mode): Sets pin mode (INPUT/OUTPUT).
- digitalRead(pin) and digitalWrite(pin, value): For reading/writing to digital pins.
- analogRead(pin) and analogWrite(pin, value): For handling analog signals.

Timing and Math Functions

Timing functions include delay(ms) for pausing the program and millis() for tracking elapsed time.
Math functions, such as min(x, y), max(x, y), and random(min, max), help with numerical operations.

Serial Communication

Serial functions facilitate communication between the Arduino and a computer or other devices:
- Serial.begin(rate): Initializes serial communication at a specified baud rate.
- Serial.println(data): Sends data to the serial monitor for debugging or output.

Appendix of Practical Examples

Illustrates practical applications including digital output/input, PWM output, potentiometer reading, and servo control, bridging theory with hands-on implementation.
