I am using the serial port to drive a transistor as a switch - see attached.
The serial signals every 3.5 secs and works as needed. When something odd happens instead of 3.5s - the serial signals in 1.5 secs from last trigger instead of 3.5secs.
Anyone know how I can drive another transistor as a switch if the timing is 1.5sec instead of the normal 3.5secs? So if timing is around 1.5sec since last signal DTS signal fire both transistors but if 3.5sec then only fire the one.
I want to use the same serial DTS line but trigger a second transistor if timing between last is 1.5secs but not fire when it is 3.5secs.
Thanks
