Control Your PC Volume with ESP32-S3 and Makerfabs MaTouch Display

Did you know that the ESP32-S3 can be used as a HID (Human Interface Device)? Basically, you can program it to act as a keyboard or mouse. I am using this feature in this project. This is the Makerfabs MaTouch 1.28' rotary display, and I am using it to control the volume on my PC.

That is such a clean interface. There are many UI developers who should take a design class from you. Beautiful design

[@VolosProjects]

Tnx henry.

[@tubeDude48]

I'm sure many people don't realize the level of coding you can do. Your gadgets are always amazing! Thanks, Volos. 👍

[@lohikarhu734]

I guess that one could add other control functions, using buttons on the screen to change menus....very nice looking!
As usual!

[@ChuckThree]

Ohhh, that would be amazing for aftermarket car stereos! Annoying almost none of the use volume knobs

[@StriViK]

The question is can we use a esp32 to make a aftermarket stereo or a raspberry pi based radio

[@alejandroperez5368]

@@StriViK And why would you want to do that?

Amazing thank you

[@nishad2m8]

Cool 😇. i need to try this on davinci resolve

[@NamasenITN]

It seems the rotation is not very smooth and low friction. Is it meant to be that way?

[@qbalsdon]

This is so amazing! Have you tried making a BLE HID with the ESP32-S3?

[@VolosProjects]

Thank you! Yes i used bluetooth keyboard library few times

[@ingusmant]

You could add controls for other audio options like bass, treble, equalizer, etc

[@akulahpathub]

That would need implementing comunication with the audio driver.
I never know keyboard shortcut for that function. This device only mimic keyboard device, i guess.

[@giusepearturo]

if you get this compatible with ESPhome, woul be the major add to the project until now

[@silverback3633]

Excellent job. Compare to LVGL, your graphics are order of magnitude better. I believe you are the only one doing the bare metal coding for small screen and it shines.

[@VolosProjects]

Thank you :)

[@arp_catchall]

Great for thermostat. Still wish it came with better case tho.

[@maglevize]

What font are you used for the number? It’s just perfect between clarity and minimalism

[@VolosProjects]

hello, name of font is Agency

[@fermintm]

I also think you could control the volume via a bluetooth connection.
Very nice project!

[@alejandroperez5368]

But if the computer is connected to a soundbar via bluetooth, I don't think you could achieve it. I don't think the bluetooth adapters in PCs or laptops are usually multipoint capable, if that's what the technology is called.

[@JB-fh1bb]

​@@alejandroperez5368that would make a common use case impossible: Bluetooth keyboard + Bluetooth headphones

[@Kevin000]

Can we code this in a way that works like deej?

[@nobodyisperfect1564]

I had the same Idea, but with a Microphone. Against the loud Ad. and Music in YT.

[@Zortan12]

❤

[@zetasonics7584]

Random, but where do you get those usb-c cables from?

[@VolosProjects]

I got it with some of lilygo board. But you can buy it on temu site

[@bayliner4387]

I like it, but I dont see the code in the description

[@VolosProjects]

Sorry i will put it right now

[@leooblak5214]

Hi! I like very much your projects. It's possible to hire you for some small ESP32 projects? Leo

[@SublimaSono]

Hi. Is reasonably effort to adapt this to raspberry?

[@VolosProjects]

I dont know, i havent used rpi for a while.

[@MrKingChannel1]

how can i use this in my car

[@VolosProjects]

it depends what you want to control.

[@IbnBahtuta]

The amplifier for my PC came with a volume control, if yours didn't send it back. If your keyboard didn't come with a volume control send it back. smh

[@hightech_lowlife]

bought this board and downloaded your code, but getting an error on upload...
who wants to help a noob?

[@mkimerling]

I am also getting a fault "ledcSetup was not declared in this scope"

[@VolosProjects]

You need to downgrade your esp32 boards to version les than 3.0

[@mkimerling]

@@VolosProjects Thanks! that did it

[@veitklub]

you could do this via bluetooth, then you don't need to connect the cable. to the laptop ...

[@VolosProjects]

Yes i know but then i need to find way to power board.

[@akulahpathub]

Is it power hungry device ?

[@veitklub]

@@VolosProjects well it could be powered by a power outlet, but at least no plug at the laptop...
