Hi all
I have a qn on IR sensors.
My IR sensor (juz the device connected to controller with resistors) is activated (thru digital or analog ports) regardless of whatever object is placed over it, black or white. I need it to be activated by a reflective white surface onli, and not juz any black surface.
The sensor shows a slight difference in volt reading/ analog output reading between a white surface and a black surface. I need it to show a very large difference so that the robot can know distinctly when a black surface is passed over it, or when a white surface is passed over it.
How can i go about doing this?
Thank you for advising
