2.7 Video 7: Arrays and Loops in Arduino Programming
This tutorial is designed to provide a thorough understanding of using arrays and loops in Arduino programming,
specifically tailored for beginners using the ESP32 module.
• Introduction to Arrays: Explains what an array is, how to define it with multiple values, and how to access and
modify its elements.
• Defining and Filling Arrays: Shows how to define an empty array with a predefined size and fill it with values
using indexes.
• Using Loops with Arrays: Introduces different types of loops - for loop, while loop, and do-while loop -
and their usage in accessing and modifying array elements.
– For Loop: Demonstrates iterating over an array’s elements, with detailed explanation on the loop’s
structure and incrementing index.
– While Loop: Explains the while loop that executes code blocks based on a condition and showcases
decrementing a value until a condition is met.
– Do-While Loop: Focuses on do-while loop which ensures the code block is executed at least once
before checking the condition.
• Practical Examples: Includes examples on updating array values, printing all elements of an array, and using
conditional statements within loops.
