MikeMI, I'm using the counting system for a public restroom so I was thinking about using a infrared beam at the entrance door. once someone breaks the beam as they enter, it would trigger the counter to start counting.
Conrad Turbo, that same question came up durng my first presentation and I decided to use an entrance and and exit door and with the infrared beam being the sensor to trigger the counter to start counting, the beam will be designed to count legs like traffic counters count the tires and for a handicapped person, a button will be used to determine their entrance. Do you think I will still run into problems?
