Back to working away from home so time to work on my code. At the moment when ever  a PIR is triggered the controller will latch a really for a set time if the PIR remains sensing something the controller does not recognise this. Im quite sure that this is because i need to make the PIR thats sending the signal to check to see if the pin is still LOW. I believe that adding debounce (I think) will help with this. Hopefully i have enough parts with me to build a couple test units or testing will have to wait until the weekend.
