deej - Arduino Volume Mixer 

Its things like this that reinforce my choice to have a large collection of components on hand. When inspiration strikes, having everything you need available is an excellent feeling.

Awesome video, I'm glad you like the project :)

Just what the doctor ordered! You hit right on the nail head! Thanks so much!!

I found someone who made his own 3D printed volume mixer in a lovely little tech related group on facebook. A few people were actually interested in buying 1 from him, including me. A couple weeks later and he has decided to actually 3D print some and sell it to the ones who are still interested. I'll hopefully get mine this week and hopefully set it up correctly and get it to work! This is literally what i've needed for 3+ years and i'm so happy i stumbled upon that post on facebook. I could also obviously follow this video if i don't get it to work but the guy making it and selling it were going to make a step-by-step guide for me too, so that's great!

I 3d printed this and made my own shell for this and it is really an amazing adjuster, adjusting Spotify and my games is so so so convenient, I would totally suggest anyone to make this, so so simple and easy to make changes to the code. 10/10

i made one myself yesterday and your video helped me a lot. thank you!

This made everything much more clear for me thanks!

I like the pretend volume adjusting at the end lol. Nice project and as mentioned by others i think i have the parts lying around to do this one!

Thank you great project it helped me a lot really appreciate it :)

GENIOUS!!! I`VE DONE WITH ELEGO R3 AND EVERYTHING FINE!!! CRAAACK

Amazing video! I will try to do it. It would be great if you can add a LED display to show a graph of volume.

Perfect

Great video Adam with a real intuitive Arduino program part. I’ve just 3d printed the 7 segment led clock but the RU-vid video is really sketching both the wiring and programming, I’ve attempted it mostly by studying screenshots of the video!! Nightmare...alas I’ve ran into a problem...it’s not working lol

Yeah? What? Why you keep calling my name :D

Nice

This looks like an awesome project, and I am probably gonna pick up the parts to build one. I was curios how hard would it be to make a button to change audio output between speakers and headphone? Thanks!

👍👍

Nice!

Nice video. Escpecially the printed box ! Just what I need... ;-)

I tried building this although i used sliders instead. Having some issues, when at the serial monitor, all of the numbers stay around 1000 whether I move the slides up or down.

I've bought a PCB for a "split ergo" mechanical keyboard (Lily58) which features at least one rotary encoder. But haven't gotten to soldering it yet. Would like to have more encoders. Also for zooming on a website which has become somewhat of an issue on a 4k screen and side by side layout. My ideal keyboard would also have a trackball instead of a central spacebar. No more switching to mouse for a few little adjustments.

Nice project - any idea if it works with microsoft games like solitaire adds?

I wish there was a 10$ ready to use one from the local (or oversea) retailer.

what a great project! had the same exact problem myself for many years. I have since gotten used to hitting the media keys + and - volume on my keyboard. But While holding down another button. But my problem now is that i cannot use multiple keyboard modifiers in conjunction with those media keys. To specify and multiplex the volume control across different channels. Why do i bring this up? well because most of the time we are only ever adjusting the first 1-2 of the most commonly used audio channels. And then very much less occasionally we need for something less common like skype etc. So being able to do everything 'by feel alone'. without having to look down every single time becomes important. SO: rather than have a bank of completely equally sized and equally spaced faders. it should be that the usability is prioritized. For example if you have 5-6 such audio faders. Each for a different channel. Then the more channels you have it then becomes slower to feel your way across to distinguish between the middle channels. For example channel 4 much be used much less often than channel 3. Yet you can frequently find yourself 'by feel' being unable to distinguish between 3 and 4. Since they are right next to each other. So for this project I would suggest a customized grouping of controls. Tailored to how much you relatively use each one. With a combination of faders and different style rotary pots. Different sizes, spacings and locations. You may achieve an extra level of speed when attempting to aquire any given control. The muscle memory of reaching for something. Through appropriate differentiation.

nice video and for those with out a 3D printer like poor me I can still do it but in a project box:-)

Thanks Adam. At 14:34, your comment, 'The code is straightforward...' had me laughing. Most people, who have no coding abilities, would disagree with that assessment. 😉 It's an interesting, if somewhat overcomplicated, way to adjust software volume levels, leaving another item to locate on a busy workbench. But I do like the idea. One question arises though, and please forgive me for asking it, because I rarely see Windows: Wouldn't a customisable on-screen mixer be much more convenient and tidy to use? Surely somebody must have designed one for the OS? Windows has been around for over 35 years, after all. Of course, the question is begged for those using Linux, because several decent and customisable Open Source mixers already exist.

Can you also include music buttons: Play/pause, previous, next. To this device?

Looking forward to trying this! What M3 inserts did you use M3 x D x L ?

hi there , is it possible if i want to make each knob to increase 20% or capped at 50% volume?

Hi, great vid. Trying this build. Unfortunately the nano i have does not do anything after uploading the code. Question: 1. Would there be a way to make this code work with an Arduino Pro Micro? 2. I have no coding knowledge, do you perhaps have a code on hand that you'd be able to share, please? The Pro micro codes from Nerd Musician is too complicated for me to implement :(

thats windows for you!

If you adjust the volume through the PC software will it make the knobs automatically turn to the right volume level on the DEEJ?

I always wondered where Robin Leach went after Life Styles of the Rich and Famous.

If anyone is looking for a great software alternative try EarTrumpet in the Microsoft store, it's free but only works on Windows 10.

Does it have to be an original Arduino Nano or clones like CH340G will suffice?

Hey if you don’t mind, what exact wire or cable did you use? I want to do this but I’m not sure what kind of wire you used to wire everything together

Anyone know how to make the software that connects to the windows audio mixer? Or how to read the code of deej.

Im a little late to the party here, but i got a few B10k potentiometers - but the reading goes all the way to 4095, and even starts reading values from the other potentiometers if i turn it colpmetely. What am i doing wrong?

Not something i would use myself, but i cant help thinking it needs a level of complication and is missing LED bar graphs to show volume level lol

Can it be done with arduino UNO?

Does it make a difference what potiometers i use? Because i have 2x 100k 2x 50k and 1x 20k. The serial monitor always write 1023 on the 100k and 50k, and the 20k varies between 995 and 1017.

My numbers arent stable they just go up and down, or just to random numbers. What do i do?

Work arduino uno?

its blue

Hel 600

If this had RGB lighting it would be perfect for gamers lol. 🙂
