Using PIC16F84A as a timer for several I/O

[OptimusPrime]

WOWWWW guys, i didnt think this would be that complicated.

Ok let me try to explain once more, u seeeee i already have the tracking circuit made, i got the 2 LDRs (FYI: these LDRs compare the light intensity and then move motor to a postion where there is equal light falling upon them) and the motor running at 12V, everything is setup, basically i have finished the tracking system for azimuth direction.

All i want to do is thaaat instead of making a whole new tracking circuit for the vertical direction, i want to use an automatic timer. so now i should have one tracking circuit, 2 LDRs for azimuth direction, motor for moving panel in azimuth direction, 2 LDRs for vertical direction, and a motor for vertical direction. All the automatic timer should do is that to switch from one motor and a pair of LDRs (azimuth direction) to the other motor and a pair of LDRs (vertical direction).

is there any project anywhere of this nature that i can refer to?

Guys i seriously appreciate all the help u have provided, i mean believe it or not, this was my first time ever posting a message in a forum, and im really glad to see the kind of respose i have recieved.

thanks once again, any furthur help would be appreciated,

take care

OptimusPrime, All you need is a 4 pole double throw relay. 2 contacts for the motor output from the tracker to the motors and 2 contacts for the 2 sets of LDR's. Program the PIC for 60 second pause then toggle 1 of the outputs to drive a transistor to switch the relay... Pretty simple I think...
