Using the TCRT5000 Photo Reflective Sensor as a Line Following Sensor

In this video we are looking at how to use the TCRT5000 photo reflective sensor for line following.  Line following will be utilized by the Zoomie for guidance during all straight line driving.  We will cover the many aspects of the sensor including how I tested the sensors analog output over a variety of different line types.  

PICO / Micropython specific discussions include:

• Measuring read time of the sensor
• Writing testing reading to a file inside the PICO
• Graphing the analog readings to "see" the line transition

Cheers!
