I found a description on it here http://www.kptechnologies.com/forums/viewtopic.php?t=73 but I can not find the module they are talking about. I also searched on google and that was all that came up. Anyways I want to prank my friend by hooking the horn up to the breaks, but I want to have a circuit that can honk the horn after the break is pressed x amount of times OR after 30 seconds of continuous breakage. Does anyone know of a module I can buy that could do this or how to build a circuit that could? Thank You.
