Introduction

The DFRobot Line Tracking Sensor for Arduino can detect the white lines against a black backdrop and black lines against a white backdrop. The single line-tracking signals can provide a stable TTL output signal to esnure accuracy and reliability.Optionally, a multi-channel mix is easy to install with the necessary line-tracking robot sensors.

• Version Update
  The best distance between objects such as the ground and the sensor is 1-2 cm.
  V5 removes the variable resistor and is therefore easier to use now.
