one more thing, (just to make it a bit simpler, base this on button examle) when the button pin goes low there would be a delay of upto 30seconds before the LED goes low, but if the button is only on for a period of 10seconds then the LED will only stay on after the button goes low for 10seconds. hope you understand what i mean there
also the delay time needs to be without a delay like the example blink without delay.
thanks joe

hi there think i have figured it now
int ledPin = 13; // LED connected to digital pin 13
int button = 2; // button pin
int count = 0; // Our blink counter
// The setup() method runs once, when the sketch starts
void setup() {
// initialize the digital pin as an output:
pinMode(ledPin, OUTPUT);
pinMode(button, INPUT);
}
// the loop() method runs over and over again,
// as long as the Arduino has power
void loop()
{
if (digitalRead(button)== HIGH) // buttin when high
{
if (count < 1) {
digitalWrite(ledPin, HIGH); // set the LED on
delay(1000); // wait for a second
digitalWrite(ledPin, LOW); // set the LED off
delay(1000); // wait for a second
count++; // add one (1) to our count
}
}
else {
if(count == 1) count =0; // resetting the count
}
}

i have written in the code which bit i want to run once void loop() {
int val = analogRead(ionisation);
//--------------------------------------------------------------------
if (digitalRead(heatbutton)== HIGH) {
// ** from here need's to just run once **
if (digitalRead(ionisation_in)== HIGH) { // if ionisation swith HIGH
if (val >900) {
digitalWrite(solenoid, LOW);
digitalWrite(lockoutled, HIGH);
digitalWrite(heatbutton_feed, LOW);
}
}
else {
if (digitalRead(photo_pressure)== HIGH) { // if photo swith HIGH
digitalWrite(lockoutled, HIGH);
digitalWrite(solenoid, LOW);
digitalWrite(heatbutton_feed, LOW);
}
}
digitalWrite(relay230_24, HIGH); // 230V out put to ignition
digitalWrite(fan, HIGH);
digitalWrite(ignition_fan_2, HIGH);
delay(2000);
// ** to this point **
//---------------------------------------------------------------------
if (digitalRead(saleswitch)==HIGH) { // sale switch if HIGH

hi there
i have a code that runs when an input is high which obviously runs over and over continously as long as the button is high but the first half of the code i only want to run once but obviously if the button goes low then high again it will reset and will obviously do the first half again once?
thanks Joe

hi there
i have been playing with different resistances. im up in the 2000k to get it to work on my test rig on my finished product i might be able to get it lower than that but i was wandering is it ok to use these sorts of resistances?

hi again
i have made bit of a rig up and ran your theory above and i couldnt seem to get it to work at all. i think there is a bit more to it than i originally thought ?
