Hello,
I would like to use a car horn with the use of an garage remote control and an arduino, but I don't understand the possibilities.
I would like to use this sort of garage remote (not necessarily this specific one, but more for the idea) and recieve it with an arduino RF module, also on 433MHz.
Is it possible to connect these 2 and read the signal on the arduino? Or is it only possible to use the Arduino RF receiver with the Arduino RF transmitter?
Thanks in advance
Google 433Hz remote and see what you can get.
google 433hz remote Arduino
and see what has been done with Arduinos.
as for the horn, you would be best to use a relay. mechanical or SSR.
I suggest a 12 volt relay because the car horn will be 12volt and you will have 12volt for that.
also, because the relays you can buy are great for beginners and will make your project a success faster.
Thank you for the reply.
I have already tried googleing these and other things to find more information. I understand that you can use the RF modules I posted a link to.
My specific question is if it is possible to use a garage remote control and receive that signal with the arduino, because the remote is much easier to carry around than an complete arduino.
I would tend to connect it to the headlights. Blip the highbeam lever to operate.
Neighbours are going to get a bit nasty if you blow crap out of the horn every time you want the garage door to open.
Blowed if I can see why a press button which is already there does not suit you though.
Garage remote control transmissions are almost always encrypted with a rolling code, so you won't be able to make sense of them with a simple receiver, or duplicate them with a simple setup.

my point is that there are .key fob remotes that work with Arduinos
the garage door remotes tend to have rolling security codes.
and great layer of protection, but also an added layer of difficulty.
as a note the garage door remotes are usually paired with an inside relay board.
so the remote is paired to a specially designed receiver .
that receive can easily be tied in to the Arduino.
just some clever interconnections and Bob's your Uncle.

Thanks, but my bike does not have a highbeam lever. I also don't want to use the remote to open my garage, but a garage remote is much easier to carry around than an arduino with battery pack and more.

Ooh I see, I'm sorry.
How can you find out which ones are compatible with arduino? And how can you connect them, since the output is 12V and the input pins to an arduino are 5V.
Would this one also work?
Thank you very much for the help.
The one shown turns 4 relays off and on.
You can connect each relay to an input pin
The remote controls the relays
The relays signal the arduino.
Relays are made of three circuits.
The contacts ts are isolated so the arduino does not care
The coil is higher power than the arduino can provide and is semi isolated. Again the arduino does not care
The signal is the only thing that the arduino cares about
I get it now, you can just connect 5V from arduino to the relay +, and then the relay - to an input pin. Thanks, now I will never lose my bike again.
Relay contacts common and N/O. Or normally open.
Although you may be a le to use the coil wires there may be a damaging spike.wben the coil changes state to off
Goofle motorcycle alarm. Dirt cheat units are available
Might be what you want

What do you mean with "a le to use the coil wires"?
