    Hi Bob
    Thanks for that.
    Call me a lazy 'person' but I wanted to try and get it all automated.
    Don't fancy all that CV stuff that was part of the ESU write up
    I will not give up! Yet!
    Cheers
    Pete

    Hi Ian
    Now, there is another way!
    Not sure how many boards/tea lights I would ruin with my soldering 'skills'.
    Certainly worth a look if only for buildings. Less wiring.
    Is there a remote for each light or will one remote switch all the lights in one go?
    Cheers
    Pete

    hi Pete
    here is what you need
    1, 3volt battery
    2, leds ( the number you need for the coach0
    3,pir sensor
    4, transistor.
    here is a article that shows how the sensors work.

    If you want me to I can draw up a circuit for you and a list of bits you need.
    be seeing you
    Bob

    Hi Bob
    Looks interesting.
    I have heard and looked, (a little bit), at Arduino. Not sure if I know how it all works.
    I note that it is a PIR that measures IR light.
    My question is, if the coach has halted and the lights have gone off, if I cast a shadow over it, will the lights come on?
    I am not trying to be pedantic and I am enjoying the posts.
    Possibly I may learn something.
    Out to dinner now.
    Will continue this in the morning.
    Cheers
    Pete

    Forget PIR's. They do not detect light, they detect motion by sensing heat (IR). ie humans warmth. Yes you could wave your warm arm over the top to start them, but the train running will unlikely keep them on, so would have to be on a timer. Plus the sensor is huge!

    Many thanks.
    I am putting this on the back burner for now until I get back to the UK.
    Also, many thanks to Bob and all the others.
    It is a friendly forum for sure.
    Cheers
    Pete
