# Arduino Cheatsheet

## Overview of unique features

- Microcontroller platform
- Simplified C++ programming language
- Integrated development environment (IDE)
- Built-in functions for interacting with hardware
- Wide range of compatible sensors and modules
- Real-time processing capabilities

## Variables

// Declare a variable

int x = 42;

// Declare a constant

const int y = 10;

// Declare an array

int myArray[3] = {1, 2, 3};

// Declare a string

String myString = "hello";


## Functions

// Declare a function

int add(int x, int y) {

return x + y;

}

// Call a function

int result = add(3, 4);


## Loops

// Define a for loop

for (int i = 0; i < 10; i++) {

// do something

}

// Define a while loop

while (condition) {

// do something

}


## Conditionals

// Define an if-else statement

int max(int x, int y) {

if (x > y) {

return x;

} else {

return y;

}

}


## Interacting with hardware

// Set up a digital pin

int ledPin = 13;

void setup() {

pinMode(ledPin, OUTPUT);

}

// Turn on and off the LED

void loop() {

digitalWrite(ledPin, HIGH);

delay(1000);

digitalWrite(ledPin, LOW);

delay(1000);

}
