IR Distance / Line Tracing / Line Tracking Sensor

This module uses TCRT5000 Infrared Transmit and Receive sensor to determine the distance.

Ao - Analogue pin output level correspond to the distance measured.
Do - Digital pin output correspond to the adjusted sensitivity to indicate if above or below reflective value.
Vcc - Positive Power input
Gnd - Negative Power input
