Arduino Drum Machine

A drum machine built from an Arduino board, some resistors, two pots, two DIP switches and two 4021 shift registers.

One of the pots controls the sampling rate and the other controls the delay between notes.

The two DIP switches set the notes. There are eight beats in the loop. Each beat is set by the combination of the two switches.

what happens to the camera :S

[littlescale]

um what?

[Twistx77]

I agree with gaussman something was happening to the camera. Don't you see the image gets like dirty ever 2 seconds or so.

[littlescale]

hmm yeah i think it could be the codec im using for compression, perhaps? is that possible?

[Twistx77]

yeah it is posible if you did any processing after getting the video from the camera.

[littlescale]

No, not at all, but I just used quicktime pro to compress the video from the camera (which was a .mov file to begin with).

[Anxo512]

i think that the bass produce a resonance and vibration on the optical parts of the camera

[ImmortalDestructor]

The slight shakiness is likely caused by the camera being too close to the speaker.

Awesome Jungleee Music @ 2:02

1000 stars for this project

[BRYAWN]

it's definitly not bass that makes the camera move! it moves from the beginning, and it's not synch with the music...

@gaussman08 camera feels that beats :)

[geeekbit]

@littlescale I think either the camera or QuickTime was dropping a keyframe or something, it's not a big deal though :P Neat drum machine littlescale :)

@gaussman08 littlescale is poisoned! He should heal at the nearest Pokemon Center! ...sorry, I had to.

@Twistx77 electromagnetic fields by the sound box

@littlescale

he means the little distorsion for every drum

[punisher17011990]

do u use "reverse"  shiftregisters for the digital input?

[Soulrider2012]

@ImmortalDestructor I don't think so as the 'pulse' of the distortion doesn't match the sound at all. The pulse is perfectly timed and not with any beat from the music. I think it's some kind of signal interference from something.
