“ANDI is a machine that generates a random rhythm at the push of a button. Each beat is unique and can be tweaked with five knobs. ANDI is the result of a university project that was about inspiring musicians and examining new ways to work with drum beats. More information about the project can be found at andinstruments.com
During the design phase of ANDI a lot of inspiration was taken from the maker community and especially from exciting projects here at Instructables. To return the favor I have written this Instructable on how to design the electrical circuit for the ANDI beat generator. It is a simple circuit with five rotary knobs that controls the playback of short drum sounds stored on a micro-SD card via an Arduino Nano.
This Instructable covers the making of the electronic circuit and the code programmed on the Arduino and the drum sounds used are found here. The code is explained with comments in the code-file and I will not go in depth in the code in this tutorial.
ANDI has an outside of sheet aluminum and plywood and I have not included the making of the outside in this Instructable.
If there is an interest in a thorough explanation of the code or how to make the enclosure this it will be added in the future.
Otherwise this gives you the freedom to design your own enclosure for your ANDI-beat generator.”
