Hello Everyone,
I need to use several different remote control units to control some props in a haunted trail we put on every year for charity. There are a ton of cheap China made 433mhz remote control systems on Ebay that will probably work just fine. I'm sure you guys have seen and used them. They come in 1,2,4,6,8,12,etc channels and usually cost less than $20. Here's a link to a 4 channel model for reference (LINK).
The problem is I need to use several of them in the same location. I've bought a couple and I can't see that there is a way to make sure that RX'er "A" works with TX'er "A", "B" works with "B" and so on. I'm not sure what this action is called (encoding/decoding maybe) (or maybe "addressing").
Is there a simple circuit or IC that I can build and add on to these? I'm not an electronics engineer by any means but I can follow directions and build a circuit from a schematic if I've got one.
Thanks for any help or direction you can give.
Greg
