Hi, I'm working on a project that needs an RPM switch. I've seen a few idea's searching around on google, but I'm looking for the most simple way to build an RPM switch to send a high/low signal to my pic. It would need to switch at roughly 350rpm (I'll have to adjust this once I try it) so the pic knows when the engine is running, versus when it is off. The pic controls starting, so I can't just use the oil pressure switch, etc as an input instead. Thanks
