Here, we are going to learn about while and do.while loops. In the previous tutorial, we learned about the C++ for loop. That was just a simple example  we can achieve much more efficiency and sophistication in our programs by making effective use of loops. Then instead of writing the print statement 100 times, we can use a loop. In computer programming, loops are used to repeat a block of code.įor example, let's say we want to show a message 100 times.

The ‘for’ statement is used to display the value 3 times. In our example below, we use the ‘for’ statement to display the value of a variable ‘i’. Suppose if you want to repeat a certain set of statements for a particular number of times, then forloop is used.

code will follow in the next postĬonst byte Signal = 2 // sima gia na traviksei i kama tou magniti. The ‘for’ loop is also used for iterative purposes.

Here is my code : i had to remove the code because i got an error for to many words in one post. I guess something has to do with the while loop condition and the time-delay I tried to place directly new numbers in the code = Nothing I tried to put new int variable names = Nothing I tried with the same code line that i used in the mail loop to read speed from potentiometer = Nothing Relational operators test the relationship between values, for example is the number 7 greater than the number 5 or is the value that a variable holds less than 10. LAST REVISION:, 07:44 AM Sometimes you want everything in the program to stop while a given condition is true.

Part 5 of the Arduino Programming Course. Built-in Examples While Loop While Loop How to use a while loop to calibrate a sensor while a button is being read. There i can control my motor (direction and stopping it with limit switches as above, but the speed is very slow and cant change it what ever i do Created on: 26 September 2014 Updated on: 19 January 2017. My problem is in the service mode that runs in a while loop. If i press one switch then i m going to the service mode My code works fine in the "Normal mode" and i can see the speed of the motor changing when i rotate the potentiometer. If it has no signal then runs the motor in the opposite direction until reaches an other terminal switch My code in normal mode when has a signal in one pin of arduino runs the motor with a speed based in a potentiometer and stops if reaches a terminal switch connected to an other arduino pin With my code i have 3 states, one that is the main loop "normal mode", one that is the "service mode" and a third one that is the "error mode" This could be in your code, such as an incremented variable, or an external condition, such as testing a sensor. Please note that you may compare variables of different data types, but that could generate unpredictable results, it is therefore recommended to compare variables of the same data type including the signed/unsigned type. Something must change the tested variable, or the while loop will never exit. Returns true when the two operands are not equal.

I wrote a code to drive a small Nema17 motor with a A4988 driver in full step A while loop will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false.
