code issues

hi there when this code is called up in the main loop it only calls it once then does other things so this code below only does one revolution then stops how can i make this run continously until when the arduino is reset?

void LED2() {
digitalWrite(lockoutled,HIGH);
delay(500);
digitalWrite(lockoutled,LOW);
delay(500);
digitalWrite(lockoutled,HIGH);
delay(500);
digitalWrite(lockoutled,LOW);
delay(1000);
}

You'll need to post the whole sketch to get any meaningful help.

Joes, also when you do use a code box instead of quote box (because code boxes have scroll bars). To do so either click on the little button with a "#", or use "code" instead of "quote" in the brackets.

You'll need to post the whole sketch to get any meaningful help.

Joes, also when you do use a code box instead of quote box (because code boxes have scroll bars). To do so either click on the little button with a "#", or use "code" instead of "quote" in the brackets.

sorry just pushed wrong button

Looks like you need to hit some pretty specific conditions for the various if paths to call out the LED2 function.
Need to be in void oil or void gaz and saleswitch needs to be Low.
You could add some serial.prints and see if the code flow is following the expected path, or if variables aren't getting the values you expected.

Joes:
sorry just pushed wrong button

No problem...

it all works exactly how i want it to apart from the three LED blink LOCK OUTS at the bottom they only do the code in each section once when called up.

I can't see why those led routines wouldn't get called repeatedly. Of course, the led won't flash in a continuous pattern for any of the functions because of all the other delays in the code, but I'd expect them to run again and again given that restriction. What do you actually observe the led doing?

the led does exactly what it says in the code but only does it once.

Then it is time, as Crossroads said, to add some print statements to your code to see the execution path.

I just had a question. Does it not have to be in the void loop part of the sketch to run over and over again or will it do that command anywhere with in the sketch. For my own curiosity.

Thanks

good question

Cut and paste into bottom of void loop. Let me know?

mhastie1234:
Does it not have to be in the void loop part of the sketch to run over and over again or will it do that command anywhere with in the sketch. For my own curiosity.

Your entry points are setup() which gets called once, and loop() which gets called repeatedly. If you want your code to run repeatedly, put it in loop() or in a function called from loop().

ok
i have just changed it all about so everything is now in void loop the only problem is that the led part to the code is running all the time istead of when its called up i think i have written up the call up command incorrectly?

A really good idea, before you post code, is to hit ctrl-t in the IDE, to sort out the indentation.
It makes it easier to read.

yes as we send we was going to try it all in the loop
