When the while loop is executed, the compiler will initialize the while loop and check the condition. For the visual understanding of the “while loop” in Arduino, consider the flow chart: The most convenient way to understand the usage concept of anything is through visual explanation. What is the flow chart of the while loop in Arduino If the condition is false, it will exit from the body of the while loop.Write any condition in the round brackets “()” with the “while” keyword, till that condition is true the system will execute the code written in the body of the while loop.The explanation of the above syntax is very easy to understand: The general syntax of using the “while loop” is: Syntax of using the “while loop” in Arduino First, we will discuss the general syntax of using a while loop in Arduino programming. Likewise, it can be used in Arduino programming. This will be a code of about 5-6 lines and will fulfill the purpose as well. This can be made easy by using the while loop, in which we can put the condition of time in the while loop that is less than 30 min, and ask the user to enter a component after every minute. If we write the code in which after every 1 min, it is asked the user to enter the component and then print it, and again after 1 minute asks the user to enter input till 30 minutes, it will consume a lot of time as well as the code will become bulky which reduces the efficiency of code Loops are very handy in any situation, especially when we want to repeat the same process according to some condition.To understand the usage of the while loop, let’s say, we have a user who has 30 components of the project and we ask the user to input the name of the component after every minute till 30 minutes. In this write-up, we will understand what is the while loop and how it works in Arduino programming. In Arduino programming, many times we have to write a code in which a repeated cycle of execution of the code is needed, to execute it we use conditional loops, and the “while loop” is one of the conditional loops.
