PROJECT UPDATE:

PIR was a snip. Works fine off a 12V battery and has a pair of N/C contacts for 5V onto the PIC.

I've managed to mount the servo into a housing and 'rig_up' a bracket to hold the cable release in position for the servo, looks good and should work a treat.

All I need to do now is finish the program. I'm off all this week but Mrs LEDave has had me replacing the garden fence No sense of priority some people!!!

I'll post my program up asap.
