How can I make LED tea lights remote control ON/OFF?


I want to be able to remotely turn off a bunch of cheap electric LED tea lights.  I have a total of 15 in a room I want to be able to turn ON/OFF with an IR remote but dont have a clue how to start.  They will be situated in votives around the room so they can not be connected together so I think I will need a circuit on each tea light.  I have looked into buying units already made but they are way out of my price range for this project.  Thanks so much for your help.

Here is a link to IR receiver module app.
And I include how I would start designing a Votive IR switch
don't worry about the values because the  start circuit was 9-12V.

You have not read the material links.
The first pic responds to a 40Khz maybe someone knows or has measured
the TV remote or you can look it up, I don't remember back when I did.

As I said it is a start where I would begin ,
I really don't have the detailed answer.
You need to do some of your own work.
After all this site is an instructable site.
TI sells 3 Volt smd individual edge triggered flip-flops.

Here is a problem for you to work on. This block design will flip every time
a signal is detected. What happens if some votives don't see the signal
to turn on and you send again ( some will turn on others turn off )
How will you fix this ??

Read some of what was pointed out for you.

Each tea lite must have an IR LDR A FLIPFLOP a state decoder receiver
and a 2 stste transmitter.

Sure look at the Related ibles on the right side of this page.
Study the IR Detector, the blue LED, the PICAXE and RGB mood.

Are you intending to use 3v smd FF to keep it small ?

RF is all around you so you would have to encode and decode.
IR presumably, would be the only IR in the room.
