Hello!
My english isn't pretty god. But I hope you understand me!
I am building an Race-track-timer.
But I don't know why the software starts/stops and resets the time in moments when it should not. Or it dosn't start/stop when it should be.
For example:
---> The time don't start/stop and the relay connect the RS-232 pin's (i hear and feel it). And the other way around. The relay dosn't connect the RS-232 pin's and the time starts/stops.
---> The time is reset although i only enabled start/stop funktion.
---> The time starts/stops/reset when I turn the traffic light to red. (There sould be no connection at all).
I have two videos on youtube where you can see it in action.
I hope someone can help me! Thanks in Advance!
