Build the Auduino Granular Synth - Part 2

Panel Art, Wiring, and Finishing Touches

In Part 1 of this project we looked at building and programming the circuit board, drilling the enclosure, and acquiring the parts and tools required for this build. Complete those steps first.

Now in Part 2 we are going to create a custom front panel, finish mounting and wiring the components, and finally instal them in the enclosure.

If you haven't already, download the Panel Art by clinking the link.

All of the steps are detailed in this video. Click to watch and follow along.

 Here are some handy wiring diagrams to help you during the building process:

Congratulations! You should now have a great looking, fully functional Auduino granular synth to add to your box of musical toys. I've had a lot of fun with this project and I hope you did too. If this series inspired you to make something cool, please let me know. I would love to see what you come up with. See you next time!


  1. Hi, I've been working on this project i could finally make it work just fine. I was wondering how you could use combined to other instruments (guitar, piano, mic, etc) to modify the sound that the other instrument makes. I don't know if I explain myself but I'm thinking about the same effect a guitar distortion works. Is it possible? Is that what the midi in upgrade is for?


  2. Hi Felipe (if you are still around), this is a sound generator only and the midi lets you control the notes it generates with either a keyboard or sequencer. Distortion pedals and other effects are sound processors but still withing the scope of Arduino experimentation. All I can say is keep looking.

  3. Hello Felipe (if you are around) Here ( is a granular effects unit that can be used with a guitar.

  4. I am at an intermediate level. I'm a third year media technologies student with some experience with Arduino, electronics, etc. How long would you estimate all of this would take to complete from start to the finished product, and what is your roughly estimated cost for all of this?
    Thanks in advance!

  5. Thank you for taking the time to publish this information very useful! OMC outdrive components

    I want to bulid it with an arduino micro, as I have one and the other partts were hard to find and quite expensive, so the DIY version costedmore

  7. yes! i did it! Many thanx! Very nice sound!
