==Introduction==
Infrared obstacle avoidance sensor is equipped with distance adjustment function and is especially designed for wheeled robots.<br>
This sensor has strong adaptability to ambient light and is of high precision. It has a pair of infrared transmitting and receiving tube. <br>
When infrared ray launched by the transmitting tube encounters an obstacle (its reflector), the infrared ray is reflected to the receiving tube, after a comparator circuit processing, the indicator will light up. <br>
You can adjust the detection distance by rotating the potentiometer knob, the effective distance range of 2~40cm. <br>
They can be widely used in robot obstacle avoidance, avoidance car, line count, and black and white line tracking and many other occasions.<br>
This module should be used together with EASY plug control board.


<span style=color:red> '''Special Note:''' <br>
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface. <br> If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module. </span><br>

==Controlling Motor ==
<br>
In the previous section, we use the obstacle detector sensor to control the LED on and off. Now, let’s try another play, controlling the motor rotating.

<br>
'''What You Should See'''<br>
Done uploading the code, when the sensor detects an obstacle, the fan motor rotates. Otherwise, fan motor stops.

<span style="color: red">'''Troubleshooting:'''</span> <br>
* '''Compiling Fails ?'''<br>
This happens sometimes, the most likely case is a library file not added.  You should be sure that all the libraries are added to the libraries directory of Arduino-1.8.5. Shown below.<br>

* '''Program Not Uploading?'''<br>
This happens sometimes, the most likely case is a confused Board and serial port, you should firstly select your proper board and port.
