Hi everyone,
I've hooked up the QRB1114 infrared sensors to the analog input ports.
Although they appear to be operating, their values make little sense.
Whether a black or white object is placed in front of the sensor, the
Handyboard reads in a low value. This number slowly returns to 255 as the
object is pulled further away from the sensor. Makes for a great proximity
sensor, but not exactly what I desired. Any suggestions???? I have it
hooked up as shown in the HandyBoard manual, 330 ohm resistor and all.
Thanks for any input.
James
