I need RF remote control circuit based on microcontroller RX and TX

I need RF remote control circuit based on microcontroller RX and TX

Up to 3-5 buttons (channels) with no battery consuption in power off state.

I see that address there is no microcontroller based circuit.

Also power is not off when switch is off.

Here is a forum is devoted to DIY RC stuff: DIY Electronics - RC Groups

I searched on DIY transmitter and DIY receiver and got many useful hits. Inclusion of the term, "DIY," probably causes the search to miss a few relevant threads, but if you leave the "DIY" out, you will get too many hits. The threads you get with the DIY do link to other threads. For example, this thread was found that way: https://sites.google.com/site/rchomesite/home

The designs are basically divided into two parts: 1) an RF section; and 2) controls, inputs, and outputs. Most of the DIY projects by far used commercial RF sections. There are a few simple RF designs presented, but I would recommend using a commercial module too. As for the projects themselves, the few I checked seemed to share only the hex code and not the source code. I am sure there are some that do give the source code in links contained within the thread.

As for no power drain when the switch sis off, that is probably something you will have to consider in your design. None of the designs I saw even mentioned it.

Do You mean on this :





TX needs some switch or redesign to fulfill your request for complete power off when no button is pressed.

tpetar thanks very much that is what I looking for thanks thanks thanks.

Can I get source or hex code, and if there some description.

How to change this circuit that power is consupted only when taster button of channel is pressed?

How to do this ?

I forgot to say that this should be very small to fit in plastic case for remote control of car alarm.
This include SMD.
