Thanks so much for that "Boffin 1" I am nost grateful! I will copy and paste (deleting the indication statements) and let you know what Happens, thank you so much once again Kind regards Rob.

Boffin 1,  you are right Junction 9 is almost a car parking space off the M25 motorway smiley.
I think that I have it sorted now? code wise, however I am not completely sure. What I would like to do is programme the recipient relay to fire more than once,  i,e, fire four times in quick succession (say 0050) and then rest for say 8(ooo)  secs, but am not sure how to build multiple delays into the programme. The fast talking and very capable US lads in their tutotials ( AKA Mr Blom mainly) leave me behind from the start. Doh! I guess I`m just thick. Is there an existing site where I can copy and paste a similar existing programme and doctor it to suit?  thanks for your help so far.

int ledPin = 13;                 
void setup()
{
  pinMode(ledPin, OUTPUT);     
}
void loop()
{
  digitalWrite(ledPin, HIGH);   
  delay(1000);                 
  digitalWrite(ledPin, LOW);   
  delay(1000);
}

The above code seemed to work after the initial problem with the port selection,  but now I would  seem unable to change the low and high periods?  from what I initially set them at, around:- low 10 secs and high 1 "sec" (thats short for seconds, GM) Any Ideas as to what I may be doing wrong? Other than grammatical errors? would be most gratiously recieved. Thanks in anticipation.

Hi Karma8  I am like many "new to Arduino users" I suspect, and am totally over-awed by its capability and flexibility. I now have it working as I want it to, thankyou so much for your kind offer. What I think happened, is that somehow the Aeduino didn`t recognose (as its own) the port that I usually use for it ie port 5 ( the easiest for me as iuts in the front of my PC) and it automatically thought it should be in 1? and I missed that, so as soon as I changed it to 5 it fired up OK and I managed to reprogramme it.

As I am a novice to the programming, I wonder if I can take you up on your kind offer, (I don`t know how to paste the programme as yet to the forum, but will soon find out I guess) I won`t waste your time I assure you,

What I am doing with the Arduino is using a single unit to operate a "burst" pump system using a solenoid valve "teed" off a peristaltic high (ish) pressure system and it works fine with a small 555 timer system at present, but I need to be able to change the bursts timing as the system calls for it ie micro secs etc I have as yet to sort the needed Arduino inputs etc and its early days as yet . Thanks again for your kind offer and help KIndest regards Rob.

Hi, I wonder if anybody might have a clue to what has happened ? I am trying to run a 12 volt vehicular relay off an arduino uno and am using the 13 pin and the ground pins (2)  on the power out! I am running the pin 13 through a 330 ohm resistor and an optocoupler to a mini relay and the vehicle relay from this (mini relay) the idea is to programme the vehicle relay to fire (high) at say 4 secs and then (low) off for say 10seconds. I have programmed the arduino with an LED using the ground and 13 pin adjacent on the pin 13 bus and when I connect the relays etc in to the Arduino, the veh relay works (happily clicking on and off) but it only works at the same timing as the standard Uno indicator light speed ie around .5 high and say .5 low? can you please tell me have I blown something or should I re-programme the arduino to read relay instead of Led? and call the new programme something else? if so any advice re any new programme would be very gratefully recieved Thanks in anticipation, Rob, UK junction 9,M25
