I am trying to hook my QRD1114 up to my Axon micro controller to tell white from black on a surface. Right now, if it is far away from a surface, it detects nothing and if it is close it detects the surface.
The problem is, it makes no difference on the surface color. I know I must have wired it wrong, but I checked the drawing a few times and it looks good. I even hooked it up to an analog port on the Axon, and it reads like 250 when far from a surface and around 10 when near a surface, regardless of surface color.
Does anyone know of a good tutorial that shows how to wire a QRD1114 for white vs black detection? Rather than for simply detecting a surface?
Thanks
