Hello to all,
I want to do a timer without adjustment, with the value set for counting.
Thank you in advance!

Hi Donald,

How about this?

Hi Benj,
They are very happy, thank you very much, more.

Mr. Benj, if I want to illuminate an led after finishing counting 9999, where you have to put the led?

[donald]

Right now, I have noticed that he was without a stop --> 0, -1, -2, etc. It would have been better if from 0000 it is stopped and an led lights up.

Hi
Here is it..what you are looking for..

Fantastic, are overwhelmed by your help Sir Martin, Enamul and Benj. Indeed it works as far as I want, thank you very much.

Hi donald,
Your welcome.

If you would like me to alter flowchart, so LCD is always showing 4 digits e.g
9999
.....
.....
0002
0001
0000
Also the numbers can be fixed so it does not move to the right when changing i.e most right digit can be fixed at x5 for example.
So you can have:

Code: Select all

 
  5678
   345    
    15
     7

Etc.

Then let me know if you want any changes and I can alter flowchart for you

Hi Martin,
Thank you very much sir Martin, I understood and I have proved and it works as you say.
For 5 digits what it has to be done?
Thanks in advance

Hi donald ,
I have created flowchart that can count from 99999 to 0.
See:

Its a bit more complicated than counting from 9999 to 0 since maximum number LCD will display from and integer is 32767
