Can I use an old TV remote and transmitter to remotely control a simple 12v light circuit?

Answer 1

Hate to be brutally honest - but if you have to ask, you can't.

It's NOT just a simple 'receiver get a signal - light goes on'.

'randombushmonkey' is quite correct in his project assesment - it's quite an involved undertaking.

A standard TV remote works by sending a repeated pulsed signal (unique to each button) to the receiver which then decodes the information & effectively sends signals to a processor that distributes the correct signal to other components in the TV.eg. power, volume. ALL of these are electronically controlled - no real switches these days!

If you want to experiment with a remote 12v light switch, there will be some excellent kits in your local auto-electrical store (eg. halfords or a motor-factors). 'Boy-racers' frequently use these to remotely (radio remotes) turn on various lights etc. All on a 'safe' 12v system.

Hope I've not offended you - it's just that this is NOT basic electronics.

Answer 2

Yes. I did this for a project once and now I'll have to remember it! Each button on the remote control emits a different frequency of infra red light, all you need is a simple receiver circuit attached to the 12v circuit.

I think I hooked the receiver up to a PIC that responded to the frequency from the receiver and started the countdown circuit that it was attached to. Anyway, I think you can get commercial IC's that can do this for you, though it would probably be simpler to also build a separate transmitter circuit rather than playing around with the remote control and finding certain frequencies that the receiver will respond to.

At the output of the IC you will probably need a relay to switch on the 12V circuit, unless the IC can provide enough current to support the light.

Farnel and RS are always good suppliers of components, but if you look at Maplin or CPC you may be able to find a complete receiver module that you can easily hook up to the circuit.

Answer 3

No you can't use a remote and a transmitter. Remote is the transmitter so what you need is a receiver on the other end (your light circuit). You will probably need some sort of logic device to activate the switch on your circuit as well.

I certainly have been married for terribly nearly 27 years now. I certainly have my t.v. interior the mattress room with my distant and he has his huge reveal interior the residing room together with his distant. No hassles and that i understand he will come searching for me while he's in a position to proportion.
