I was just reading the docs and a thought came to mind... the counter will increment when pin 4 is grounded, and can be reset upon TX. This would be great for counting traffic on the road near my house. Of course for your california types, no cars passing over the contacts for 10 minutes could either mean no cars, or traffic jam. Here in Rural SC, it means no cars.. lol.
I'm thinking a laser beam across the road to a refector on teh other side nailed to a tree or a rubber hose and air pressure switch. -- Wes --- God help those who do not help themselves.
