Using PIC16F84A as a timer for several I/O

[Archangel]

I know...I am missing something.

I think he wants to switch the circuit he has from 1 motor to the other so as not to buy / build another tracking circuit. It is doable but the issue I see is when switching from 1 set of sensors to another the calibration difference may throw things out of whack. I think all you need is a simple loop to switch a relay, something like:

loop:
PortB.0 = 0
pause 60000
portb.0 = 1
pause 60000
goto loop

EDIT: Another issue came to mind, and that is how your tracking circuit will react to having its outputs go from open circuit to loaded
being switched by a relay, I am thinking some big resistors (high watt high ohm value) joining those circuits to handle the transients, or perhaps MOVs. Better yet use FETs to switch instead of relays . Damn I must be getting old . . .
