Hi Electro Tech,
I need an optical sensor that can be "tripped" when a thin piece of paper moves past it.
Can anyone suggest a type of small optical sensor to start looking into?
My goal is to make a system where:
When the optical sensor is "tripped" it tells, through use with an arduino board (arduino.cc), a fan to move.
Any suggestions on where to start???
Thank you so much!
