![]() ![]() ![]() so if you say while(1) or while (23=23) or while(moneys eat bannannas) you repeat forever. Here is the code copied back from my IDE using Copy for Forum void setup() brackets reapeat untill the () brackets are a false statement. I already have the Serial monitor set to 115200 so once the upload was complete I opened the Serial monitor and saw the expected result I opened a new IDE sketch, selected the code in your example by clicking the button for the code, right clicked on the selected code, chose copy from the right click menu, went back to the IDE, right clicked in the edit window, chose Select All from the right click menu, right clicked again in the edit window in which the original code was now selected and chose paste from the right click menu to paste in your code to replace the selected code, then clicked the Upload button in the IDE to compile and upload the code. The logical operators are acting in complete contrary to my understanding of "or" and "and".Not being disrespectful but you are running the example marked "doesn't work" correct?Äon't worry about asking, we all make mistakes so I just tried it again. This occurs when one of the roller coasters is in the station and the other is. ![]() Objective: To execute a chunk of code continuously until two digital inputs (ie. With a while loop, however, the loop will continue infinitely until the expression inside the parenthesis, (), becomes false. when using the "logical or" operator, the conditions are treated as if i used the "logical and" and thus requires the timer to reach zero or less for the button to have an effect. Trying to help my son control a Knex roller coaster with multiple DC motors and magnetically actuated reed switches to determine the position of two roller coaster cars on same track. is 0 for no looping, 1 to loopthe starting Y coordinate.with the "logical and" operator, this holds true. while, Block, Continually executes code block until boolean condition is no longer met. If it wasnt for these forums I probably wouldnt have come as far as i did. What is wrong with it It is supposed to turn on a green, yellow, and red LED respectively depending on the voltage level from 1V to 5V. The while loop is not superior to the for loop it is simply a different method of looping. Hi guys Firstly, thanks a million for all your posts. I have this arduino code that seems to get stuck on the first while loop. My code is intended to run the motor until: the button is pressed, OR the timer runs out. A while loop, on the other hand, is a special sort of loop. The stuff inside a set of curly brackets is essentially a compound statement, sort of like parenthesis in a math expression, and its not uncommon for several to end at the same place. Open a new topic with all the necessary information about your project and you will be helped. Simply put, curly brackets are used to group together a number of program statements that must be executed as a group. Each closing curly bracket matches up with a previous opening curly bracket. In the example above Buzzer Sketch 3, the for loop starts at 200 and continues while its value is. 1 I have a program that moves a stepper motor to the right, left and have a stop button that stops the motor. in the code posted below, the conditions to remain in the while loop are listed as "logical and" rather than "logical or." Welcome to the worldbest Arduino forum ever. Click on the Port number the Arduino is connected to. This could be in your code, such as an incremented variable, or an external condition, such as testing a sensor. Something must change the tested variable, or the while loop will never exit. While experimenting with multiple conditions within do-while loops, i came across a strange phenomena that left me with no results via internet search. break Control Structure Description break is used to exit from a for, while or do while loop, bypassing the normal loop condition. A while loop will loop continuously, and infinitely, until the expression inside the parenthesis, () becomes false. ![]()
