hello there,

i posted this in the audio forum a week ago but it's actually not about audio so i thought i'd repost in this forum...

i'm thinking about designing a sequencer for bleep lab's nebulophone, but i'm new to electronics, i assumed it might be rather simple if its wire carries 5V... can anyone tell if it's the case from the pcb and schematic below? i guessed the wire was on the left of the schematic, am i right?

What do you mean by "if its wire carries 5V"?

i mean that if the sound is produced when one of the "keys" receives a HIGH signal, it's quite easy to trigger sounds from an arduino connected to all keys. have you seen the video? might be clearer... http://bleeplabs.com/nebulophone/

No the wire is a ground wire. However you can still connect the output pins from an arduino to all those input pins on it, if that is what you want to do.
