Hi everyone I'm stuck on keypad, because I want 3 products like 111 beats per minute. So if I press 1 once then it saves it as a variable of 1, if i press it again it saves it in a another variable as 1, etc... Then calculates. The code supplied is what I have so far and kind of explains what is happening, thanks for the help to those who have contributed.
It's hard to tell what's going on and what's supposed to happen, but I can tell you that all the delays between a "break" and the next "case" will never get executed, so they may as well not be there.
Something that isn't there but should be, is a pair of code tags.
Hi everyone I updated the post to an extent that if you choose a number i.e. 111 and follow the code it would make sense and special thanks to AWOL for the help and look forward this project working.
Please read the first post in any forum entitled how to use this forum. http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Hi,
PLEASE DO NOT KEEP GOING BACK AND UPDATING/EDITING YOUR FIRST POST.
You are not helping others to help you by changing the initial code you had problems with.
Each time you update YOUR CODE please post a NEW message with your updated code, NOT a message that says
New Update evryone
This forum is to help all users, so anyone who had a similar problem to you, SHOULD be able to follow how you solved your problem, by changing the initial post you are removing any hope of this thread being used to help other users.
SO PLEASE NEW MESSAGES EACH TIME, INCLUDING CODE UPDATES.
Hi,
How does the code know if you are putting in a 1 or 2 or 3 digit number?
Would it be better to store each key press and look for a # press to be the equivalent of ENTER/CALCULATE?
You wouldn't need all these IF statements to check for number of digits and do the calculation?
And you would be able to input any number of digits.
