Introduction: DIY USB Media Controller for PC

About: Hello, I'm Ak in my page you can see some creative DIY projects, Tutorials and more technical stuff. Please follow my page for regular updates.

Hello Everyone,

Today I am going to show you how to make DIY USB Media Controller for PC using the Arduino Pro Micro / Leonardo.

Using this you can control the "Volume up, Down, Mute, Pause, Play, Next and Pervious" Midea key functions.

This controller will also show the volume level in the 16bit WS2812B ARGB LED Ring / Neopixel Ring,

Step 1: Materials Used

1. Arduino Pro Micro ATmega32U4 5V/16MHz

2. Ws2812B Addressable 5050 RGB LEB Ring 16 Bit / RGB LED NeoPixel Ring 16Bit (4.8 mm Diameter)

3. 360 Degrees Rotary Encoder Module For Arduino KY-040

4. Rotary Encoder Potentiometer Knob

5. Junction box ABS plastic box

6. TTP223 Touch Switch Module

Step 2:

Step 3: Circuit Diagram

Step 4: CODE

Download the .ino code file below and open it in Arduino


Before compiling the code make sure you have HID and FastLED Library installed

This program works only with Arduino Pro Micro ATmega32U4 5V/16MHz don’t try with any other Arduino Micro controller like UNO.

Check out my Youtube video for detailed instructions.

Update : 12/25/2022 - I have been receiving more feedback on reversed LED direction for Volume control, So i have added another code, if you face that issue Use the USB_Media_Controller_Reverse.ino file

Note : Use only if you face this reversed animation issue for volume control.

Thank you all for your feedback and support.
