Hello, I need help to create a small circuit I need to convert a pulse 12 volts of a directional light from my car to 12 volts fixed, I need this to activate a relay thank you very much for your help

Hello ! I would say that you better put it with another source of direct current with its respective switch because the pulse is about turning off and ignoring or apologizing but I do not know what use you will give it.

Thank you very much, but I need it from the direcionles, since I will use it with arduino

It sounds interesting. I'm going to study that. Do you have any number of what you will put? model or something like that .... I know you occupy 12 fixed there. I want to know

Yeah, look, this is what arduino will do, that's why I need to take out the 12 fixed volts
Look at the function that the arduino will have
1 when the vehicle is moving in front of the screen only shows me an image that is the rear camera
At this point arduino still will not do any work since this is in charge of the main module
2 When the vehicle is in front of you and you put the directional one on the left, then the arduino has to activate the step of the main module so that it makes the passage from the image to the lcd
When one deactivates the directional then

Do you have the model number of your arduino activator?

If I use a mega and all the code is ready, I just need to convert the 12 volts that come out of my directions to 12 volts continue

Check the timer circuit with a transistor and relay.
When the intermittent was before the turning lever, what I mentioned earlier did not work.
The capacitor and resistance are selected to keep the relay energized for 3 seconds.

With a delay to the disconnection of about 3 seconds, which is activated by a diode from each turn output or turn signal, if it had only one token. From the output of the transistor, with a relay, you feed the arduino. The delay on disconnection, the output is activated with a pulse on the control and the delay time lasts. So with the turning pulses the arduino will remain energized. You can also do it with a cto. digital

you could put some diagram as it is that it can happen because he gave me an idea

as I see he wants if the directional goes to the left his arduino is activated. and if you then turn right, your arduino is activated with your camera. How is that voltage kept constant when the directional is a relay that turns on and off? I know what can be done I'm watching some videos right now ... wow if there is fabric to cut with all this
