Variables

Named storage locations that hold data values.

float

Stores decimal numbers (e.g., 3.14). Example code:

float pi = 3.14;

boolean Stores true or false values. Example code:

bool isValid = true;

int

Stores whole numbers. Example code:

int age = 21;

double

Stores decimal numbers with higher precision (on many Arduinos, same as float). Example code:

double distance = 12.345;

Character

Stores a single character. Example code:

char grade = 'A';

String Stores text (characters and words). Example code:

string location = "Moon";

A full tutorial with all data types, examples, and when to use them will be released soon. Please refer to docs.arduino.cc for general Arduino help
