Ks0109 keyestudio EASY plug Analog Rotation Sensor

Keyestudio EASY plug Analog Rotation Sensor

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.
Combined with other sensors, you are able to make interesting projects by reading the analog value from the IO port.
Note: this module should be used together with EASY plug control board.

Specification

Connector: Easy plug
Supply Voltage: 3.3V to 5V
Sensor type: Analog

Technical Details

Dimensions: 39mm*20mm*29mm
Weight: 9.1g

Connect It Up

Connect the EASY Plug potentiometer sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Below is an example code. Open or drag below code to Mixly Blocks and upload.

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.

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

Extension Experiment

Controlling Light Brightness

Complete the above experiment, want to try a different experiment?
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.
Let’s get started right now!

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

Test Code
Below is an example code.

What You Should See
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.
