Hi,
I modified the LED BLINK code to run 2 solenoids(followed the tutorial on solenoids) and was wondering how do I stop after a specified number of loops say 20,000 actuations? I was also thinking of using a selector with resistors so I can select the number of loops before it stops, say 10K, 20K and 30K, but thats still way ahead of me as Im a real newbie with this stuff. Just stopping the loop will be ok for me now.
Using the USB version.
Thanks
Roy
There isn't a concept of stopping. A possible solution would be to keep a count of how many loops you had executed and then not blinking after that many have passed. Something like...
void loop()
{
static int loops = 0; // this static variable holds its value between calls to loop()
if ( loops > 10000) { // if we have looped too long, then turn off
digitalWrite(LED,0);
return; // don't do the rest of the loop function
} else loops++; // don't increment after we hit 10000 or we wrap eventually
// blah blah, the rest of your loop function goes down here
}
Your loop() function will still be called continuously, but it won't be blinking anymore.
(Note: If battery life were an issue, there are ways to halt the processor, but that isn't an issue when you are plugged in.)
Thanks jims it worked!!
