Building an 8-step keyboard sequencer with Arduino

Sequencers, as YouTuber “LOOK MUM NO COMPUTER” explains, are musical devices that go through a sequence of tones one by one. While this can be done quite simply with a 4017 counter chip, if you instead substitute in an Arduino board for the counter, you can make your gadget behave normally, go backwards, or even act as a sort of keyboard using input buttons.

This particular project employs a Nano for control, giving it a conveniently small form factor to fit inside your equipment.

Since the start of building modular synths, ive always been looking for an arduino powered sequencer. but never really happy with the projects that were about. because it was still menu dives and button combinations. which is not what you wanna be messing about with! you may aswell use a computer and a mouse ha.

Be sure to check out LOOK MUM NO COMPUTER’s entire build process and a demo of the keyboard sequencer in the video below. You can also find circuit diagrams and Arduino code in the project’s write-up here.
