Hey guys,
Im looking to start a project
Where a REED switch monitors whether a door is open/closed,
If the door changes from an open to closed position,
an "x" second timer is triggered,
if then, the correct pin is entered using a keypad/array of PTM switches, within the TEN seconds, no action is taken
HOWEVER if the PIN is not entered within the time
The current time and DATE is saved onto flash memory?
Or onto a computer with SERIAL?
Just need advice and ideas
Thanks guys.
