Hi All
Ive made a infra red sensor that can sense a ball 15 feet away and using lens u
can get a more range.
you can use the same circuit as a security device and when triggered it can
swith a relay or a buzzer.
visit my site at http://www.geocities.com/macx75/robotics.htm let me know your
views.
regards
Dr Patel
