TCRT5000 IR Reflective Line Tracking sensor Interface with Arduino


In this tutorial, you will learn how to find black and white line track color using TCRT5000 IR reflective sensor. This IR reflective sensor utilizes a TCRT5000 to detect color and distance. It emits IR and then detects if it receives the echo. This sensor is often used in line following robots, auto data logging on utility meters, because this module can sense if a surface is white or black.
