In the for loop tutorial a variable was incremented 10 times and the value printed out. This is often useful when you must perform some code but then want to test to see if you should carry on repeating it.Īrduino While loop examples While loop example 0 to 9 Note: The do while loop is always run at least once. Of code that follows the expression is repeated. Here we use the digitalRead function to determine the state of a switch connected to an Arduino digital pin set as input. If the expression is true (not zero) then the block The while keyword uses the expression (within the parentheses following the the while order of the words "while" and "do" defines these concepts. The while loop is another loop control structure that lets you conditionally repeat a block of code. In this lesson we will look in more detail at how while loops work. In lesson 6 we briefly introduced while loops, and used one to pause the program to wain on user input. In most scenarios you could choose to loop with either a for loop or a while loop. Has an alternate form: the do.while loop. The while loop is not better than a for loop, it is just a different way of looping. Arduino For Loop - How you can use it the Right Way. Have to think about "how to do it"! The structure of the code i.e. The Arduino While loop: Is an alternative looping syntax to the for-loop syntax. It is true that you can use the for-loop to do both of these actions -īut it is far easier to use the while loop construct because you don't 4) Press the Upload button in the Arduino IDE and wait a few seconds while the code compiles and uploads to your board. Always execute code first then test a variable for the exit condition.Execute code until a variable reaches a set value.The most useful aspect of this loop construct is that it provides implementation of twoĮasy concepts that you may want to use when writing code: Increment the varible anywhere within the loop Outside the while loop using normal variable intialisation and you Not have the initialiser or incrementer sections - you set these up You conditionally repeat a block of code. The while loop is another loop control structure that lets Has an alternate form: the do.while loop.Is an alternative looping syntax to the for-loop syntax.There are two forms of this loopĬonstruct which make it easier than using the for-loop. You probably want to consider doing something only when the transition from released to pressed occurs, not just if the switch is pressed. It is not intended for a one-time operation. Arduino While Loop Arduino While loop: How you can use A while loop says to do something over and over, until a condition is met.
