Looking for Electronic Guru!!!

So I have been checking this new wireless camera out. It is two way audio capable. In my mind there should be a way to hack into the speaker wires and use the signal from the audio output to trigger a solenoid therefore have remote capabilities. Anyone in here smart enough to help me figure this out?

That would be an analog output. You need a digital output. Basically a relay. What kind of camera is it?

It's the blink xt2. I tore it apart tonight and found the wires and where they are connected to the board but there is a constant connection between the red and black wires weather your talking through it or not. The ohms stay the same.

I want to be able to complete a circuit when I hit the talk button in the app. But it appears to be a closed circuit system operating the speaker.

Obviously, I don't have a drawing, but I doubt that will work. If it does, it likely won't work well. I assume you are wanting to spin a feeder or drop a gate trap with it. There are ways to do it, and with an engineer you might be able to pull it off with what you have there, but I dont think you will be able to do it with the speaker. At least I have never seen a circuit that would work that way. If there is a microphone on it, there might be a circuit there for that. It will have to have some kind of switch to turn it on and off, but the speaker probably won't for what you're trying to do. I have been wondering why none of the trail camera manufacturers made a camera with a relay output for years. Wouldn't be difficult to do during the process. Anyway, have a look at this:

Problem is going to be varying voltage.

This can be done with an adruino nano. Wire the positive speaker cable inline to one of the analog pins and set the threshold really low. You can then key the mike and blow into it to activate the camera.

If it were me I'd remove the speaker all together and just attach the wires to the arduino so I didn't have sound on the other end. You would still have to speak over the mic but there would be no sound on the other end.

Most cameras have a physical button to fire the camera. You would then need to connect a digital pin from the arduino to the physical camera button to fire the camera.

Any chance I could visit with you about this? I have been reading up on this nano. Looks like it will work. Have you programmed one before?
