Experiments with Mozzi, mostly on SAMD21 chips



How to install Mozzi

Mozzi is not in the Arduino Library Manager, but installing it is pretty easy anyway.
The installation process is the same way you hand-install any Arduino library.

  • Go to and click on the green “Code” button,
    then click “Download ZIP”.
  • You will get a “” file. Rename it to “”
  • In the Arduino IDE, go to “Sketch” -> “Include Library” -> “Install .ZIP library…”, then pick your “” file.
  • Once it completes, you will see Mozzi in the list of available libraries and the Mozzi examples
    in “File” -> “Examples” -> “Mozzi”. Many of the examples will work with Scout but not use the keyboard.

Using Mozzi

  • Mozzi is very particular about what is in loop(). Do not put anything else in there.
    Instead put it in the void updateControl() function. See the sketches for examples.
