Arduino-Based Drum MachineFebruary 16, 2013

 

Circuit bender Dr. Bleep built this sweet Arduino-compatible drum machine, the Bleep Drum, with four sounds, four selectable sequences, tap tempo, record and playback, and more. Of course it’s open source and eminently hackable.

Guide for Bleep Drum code v003 (also applies to Dam Drum 2.0).

The left knob controls the pitch of the red pad, the snare.

Right knob controls the blue, tom pad.

Play – Stop and start playback of selected sequence. Light will blink white on the beat.
Record – Start and stop additive recording. Any pad played will be added to the sequence.
Light blinks red.
Tap – Tap tempo
Shift + pad = Change to that color sequence. Light will change to that color.
Shift + right knob = Change tempo with knob.
Shift + Play = Reverses samples
Play + Record = Erase current sequence.

Blue and yellow sequences start with kick on the 1 and 3.

NOISE MODE 30XX
Hold shift while turning on the device. The light will turn green. Hitting shift again will turn it pink and blinky
Green – Pots control the pitch just like normal
Pink – Pots control noise.
All other controls are the same.
