C++ for Arduino

Explore C++ for Arduino, including serial print function, variable conversion, commenting, reading variable, relation and logical operators, switch and break, and creating functions through examples.

Master serial print and serial println to display messages from an Arduino over serial communication, and learn their line break behavior with setup and loop.

Declare and initialize Arduino variables using int, float, char, and string; apply the assignment operator to set values. Print these variables to serial in setup and loop at 9600 baud.

Learn how to convert between integer, float, and string types in Arduino, using predefined conversion functions to display concatenated messages on serial output and perform arithmetic on converted values.

Learn how to use comments in Arduino C++ to document code and guide readers. Explore single-line (//) and block (/* ... */) comments, their purpose, and how the compiler ignores them.

Learn to read data from the serial buffer in Arduino using integer, float, and string reads, with prompts, waiting for input, and printing results.

Practice serial input in an Arduino project by collecting name as a string, age as an integer, and weight as a float, then display all on the serial monitor.

Explore arithmetic operators in Arduino by performing addition, subtraction, multiplication, division, and remainder, with serial input and storing results in variables.

Discover how the arduino if statement uses boolean conditions to test variables. Master if, else if, and else to execute blocks based on true or false conditions.

Learn to implement a two-number arithmetic calculator on Arduino using serial input, selecting addition, subtraction, multiplication, or division with an if-else ladder.

Explore relational operators in C++ for Arduino, comparing values with greater than, less than, equal, and not equal, and observe boolean results via serial print and if statements.

this lecture covers logical operators or, and, and not in arduino code to control decisions from serial input. it demonstrates reading two characters and evaluating conditions with or and and.

Explore using a switch statement and break in Arduino to select green, yellow, or red LEDs via serial input, configuring pin modes and digitalWrite with a default for invalid input.

Learn how to use the for loop in Arduino to repeat a block, controlling initialization, condition, and increment, and apply it to blink an LED via serial input and delay.

Study how the while loop initializes a variable, evaluates a condition, and increments to control Arduino pins 8–13, turning LEDs on and off with serial output at 9600 baud.

Explore how Arduino arrays store consecutive data in memory, access elements by zero-based indexing, declare and initialize arrays, and iterate with for loops to print values.

Explore how to define and use functions in Arduino C++ to modularize code, reduce repetition, and pass parameters or return values in setup and loop.
