==Introduction==
The sensor is based on a potentiometer. A potentiometer is also known as a variable resistor. It is a perfect demonstration of a variable voltage divider circuit. Its voltage can be subdivided into 1023, easy to be connected to Arduino with our sensor shield. <br>
Combined with other sensors, you are able to make interesting projects by reading the analog value from the IO port.<br>
This module should be used together with EASY plug control board.</span><br>

<span style=color:red> '''Special Note:''' <br>
The sensor/module is equiped 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 equiped with the RJ11 6P6C interface but have different internal line sequence, can not be used compatibly with our sensor/module. </span><br>

<br>

<br>
==What You Should See==
After uploading the code, open the serial monitor and set the baud rate to 9600, you should see the analog value is showed on the monitor. <br>

<br>
If rotate the potentiometer, the printed analog value will change within the range of 0-1023.

==Extension Experiment==

<span style=color:brown><big>'''Controlling Light Brightness'''</big> </span><br>

Complete the above experiment, want to try a different experiment? <br>
Next, you will learn how to display the potentiometer value on the 1602 LCD screen and to control the brightness of LED using a potentiometer sensor. <br>
Let’s get started right now!

<br>
'''Hookup Guide'''<br>
Connect the EASY Plug potentiometer sensor, a red LED module and 1602 LCD module to control board using RJ11 cables.

<br>
'''Test Code'''<br>
Below is an example code.<br>
<br>[[File:ks0397 18.2.png|600px|frameless|thumb]]<br>

<br>
'''What You Should See'''<br>
After uploading the code, rotate the potentiometer knob, you can see the converted value by potentiometer within 0~255 on the 1602 LCD screen, controlling the brightness of LED module.
