Setting Up
Description
Demonstration Programs
The QTI sensor is activated by placing 5 V (Vdd) on the W pin. This will cause
current to flow through the 470 ohm resistor to the LED side of the QRD1114.
IR light reflecting of the surface below will cause a change in the ability for the
current to flow through the phototransistor side of the QRD1114. The
transistor, in effect, behaves like an IR controlled resistance.
