Jan 25, 2022 · There are two required functions in an Arduino sketch, setup() and loop(). Other functions must be created outside the brackets of those two functions. As an example, we will create a simple function to multiply two numbers.

loop () function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond. Use it to actively control the Arduino board.

In this article, we will discuss while loops, do while loops, for loops. We will see how to use these loops in an Arduino program with an example project that blinks an LED only when a button is pressed.

Oct 22, 2023 · The most common types of loops are for, while, and do-while. In this article, we will explain the basic concepts and syntax of each loop, providing examples to help you better understand Arduino loops and effectively support you in building your next project.

Apr 23, 2025 · For instance, this example blinks 6 LEDs attached to the Arduino by using a for () loop to cycle back and forth through digital pins 2-7. The LEDS are turned on and off, in sequence, by using both the digitalWrite () and delay () functions .

Arduino While loop: How you can use this loop in Two Different Ways. There are two forms of this loop construct which make it easier than using the for-loop. Plus, how you can create an infinite while loop. The Arduino While loop: Is an alternative looping syntax to the for-loop syntax. Is simpler than the for-loop syntax.

Oct 7, 2024 · You can use loops in Arduino to execute a block of code multiple times until a specific condition has been met. In this article, you’ll learn about the commonly used loops in Arduino: for loop. while loop. do...while loop. loop() function. Table of Contents. How to Use a for Loop in Arduino. for Loop Example; How to Use a while Loop in ...

How to use loop () Function with Arduino. Learn loop () example code, reference, definition. After creating a setup () function, which initializes and sets the initial values, the loop () function does precisely what its name suggests, and loops consecutively, allowing your program to change and respond. What is Arduino loop ().

Practical Examples of Arduino For Loop. Example 1: Controlling Multiple LEDs in a Sequence; Example 2: Reading Sensor Data Repeatedly and Displaying It in the Serial Monitor; Example 3: Iterating Through Arrays for Sensor Readings; Common Errors in the Arduino For Loop and How to Fix Them. Common Mistakes with the For Loop: Off-by-One Errors ...

Apr 30, 2017 · I want to make a car with a motor, front lights and rear lights. I want to run them at the same time but in different loops. This is my code. pinMode(red1, OUTPUT); pinMode(red2, OUTPUT); pinMode(blue1, OUTPUT); pinMode(blue2, OUTPUT); pinMode(front1, OUTPUT); pinMode(front2, OUTPUT); pinMode(back1, OUTPUT); pinMode(back2, OUTPUT);
