timer

Question

i have coded a counter it works fine itself, but i made it start from 100 and want it to count to 0. now it shows : 100 990 980 970 ...

How do i make it show 100, 99, 98...

Answer 1

Without your code that is difficult to say. Normally you would lower the counter, eg. like:

counter=100;

loop() {
   counter = counter - 1;
   // display counter
}

I have written a Blog article on this with some examples. Did you see that?

Answer 2

i added these lines of code and defined the counter as 100 at te top
