    Hello to all,

    I'm new here to the forums, so first a little bit about me..I work in aerospace and restore WW2 military vehicles as a hobby.
    I've always had a keen interest in electronics, but have never really had the inclination to pursue it further until now.
    My knowledge is very much entry level, so I hope I don't become a pain with my questions :)


    Would it be possible to use a 433mhz transmitter like this one?... 433MHz RF Transmitter Module

    with multiple receivers like this one?... RF Receiver Module

    What I want to do is transmit a signal (from a single transmitter via a momentary type switch) to 4 separate receivers.
    The output from each receiver will only be to make a lamp flash on and off.

    I would like the receivers to work in pairs, for example - pushing a button on the Tx will send signal to 2 Rx's activating a lamp, then pushing another button on the Tx will activate the other 2 Rx's. Thats really about it :)

    Probably really simple stuff for you guys, but I'm still learning here.

    So am I on the right track?

    The answer is Yes, you can. But you have to do it as recommended by the product web site...

    I dont think the distance would as far as 1000m as in the advertisement.:D

    Try google and download the datasheets of HT12E and HT12D in pdf file format and read them through. Ask the questions here if there's anything you dont understand.:)

    Thanks Allen,

    I've downloaded the datasheets and starting to read, I'm sure I'll be back if I'm having trouble understanding it all :)

    Thanks again,
