2-wire buzzer for lost alarm
« on: April 17, 2016, 09:19:26 am »
Hey all, I recently received a loud 2-wire buzzer for when I lose my quad in tall grass. I want to put it in a switch, but only see videos explaining how to do it with 3-wires.

How would I hookup a 2-wire buzzer to a switch on my quad? I am running ppm.

Thanks

Same as others i think.....
On servo connector you should have Gnd, Unused, Signal, right ?
Buzzer is also connected to battery ?

I thought that it was (+) (-) (sig.) I'll fiddle around with it, see if I can get something going.
