We will connect 3 pins of the sensor module with Arduino. These include the VCC, GND, and OUT pins. The VCC will be connected with the 5V pin from Arduino. GND of both the devices will be in common. We will connect Arduino digital pin 2 with the OUT pin of the sensor. You can u...
The line tracking module is the type of infrared sensor module, which consists of two infrared sensors such as an infrared transmitter and an infrared receiver. It has almost the same working principle and construction as well as with infrared obstacles avoidance sensor module, but the only differ...
