Mixuino is a windows audio mixer build with on a Arduino nano and controlled by a python program. It uses 4 slide potentiometers feeding analog input into an Arduino nano that sends the values through serial to a python scripts that handles volume management in the windows machine. You can also add an optional push button to mute/un-mute the speakers.

I also have made a PCB for ease of instalation + a 3D printable enclosure for the latter so you can build your own Mixer.

This is my first Arduino projects and first "big" program so please bear with me :)

Usage

UI

Each checkbox corresponds to a running process and/or a process stored in the config file, ones stored (therefore selected) are checked, moving that slider will change the volume of selected processes (1st slider is for master volume)

Hide to systray hides the window, the window can be revealed again from the systray icon option Show

There is also a checkbox than when checked changes the hideDefault value if you want the window to be hidden at startup

The options available refreshes and changes (if new programs are opened or others closed) when the mouse hovers any of the scrollable frames

To close the application you can just close this window or close it with the Exit option in the systray icon

Config file

To run the program you require processes.yaml file with the structure :

hideDefault: false
slider1: []	
slider2: []
slider3: []

The values are the processes each slide changes and can be changed manually or through the UI

Getting started

Software

Required libraries:

Python

• Using pip

comtypes==1.2.0 # To communicate with the ports

Pillow==10.1.0 # For opening the image for the systray icon

pycaw==20230407 # For audio handling

pyserial==3.5 # To read the serial data sent from the arduino

pystray==0.19.5 # To create and manage the systray icon

PyYAML==6.0.1 # To edit the Yaml config file

customtkinter==5.2.1 # To build the UI

pip install comtypes

pip install Pillow

pip install pycaw

pip install pyserial

pip install pystray

pip install PyYAML

pip install customtkinter

Nothing needed for the Arduino

Hardware

Required hardware

• Arduino nano (you could use any Arduino tho)
• 4 (or more if you want to expand) slide potentiometers
• Optional push button for muting

Roadmap!

• Slider 3D Models for 3D printing! (7/7/2024)
• GUI to select which slides control which process (30/12/2023)
• Mixuino PCB (7/7/2024)
