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

So...,

Would it be possible to use a 433mhz transmitter like this one?...

with multiple receivers like this one?...

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...

This tiny RF Transmitter module is great for building your own wireless remote control or wireless link. Remote control that allows to control different devices can be easily implemented with wide range of encoder/decoder chips (such as HOLTEK HT12E + HT12D or MC145026 + MC145027 available in our store) or PIC / AVR microcontrollers. RF Module can also be used for sending data at up to 9.6KB/s.

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

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,

Leigh.
