Arduino help

[amiman99]

Hi, Can someone help me with my Arduino code?

I need my main loop to loop or do 12 times only and then stop. I know it nees some kind of FOR statement, but I don't know where to put it.

 

Thanks

Thanks Osgeld, I changed the: if loop_number < 12

to if (loop_number < 12)

 

and it worked, Thanks a lot!

welcome (and yea sorry about that I often forget the () after an if, and I didnt have arduino's software on this machine to nag me)

 

you could use a for loop in void setup() and leave loop empty to do the same thing

 

you have to have a void loop() but you don't have to have anything in it
