Bought an aftermarket keyless entry and currently I do not have the horn hooked up because it honks (gives about a 1 second burst) instead of the beep beep chirp you would expect.
My question is, does anyone know of a way to use this 12v+ long pulse trigger and convert it to a short pulse?
I'v racked my brain for a few hours thinking about it and cant think of anything....I could do it with a capacitor if I had a negative trigger, but the setup I came up with did not work well.
Anyone have any idea how to do this short of building a 555 circuit?
Or does anyone know of a chirp box that I could wire up instead of the horn?
