AREF is the pin below A0. It's a clean 5V reference voltage, so better than using the regular 5V line.

Whoa. This is amazing value. I got a bit excited and ordered parts already.

Tell me, will it also run at audio frequencies, to give interesting frequency divisions, or are the outputs too short /long for this to work.

To put it another way, Does it give a fixed length trigger, or gate, or is it pulse width of the input clock pulse?

Cheers

Lance

It works at low audio rates and outputs fixed pulses. But if you're willing to roll up your sleeves and try programming, you could add a pot or cv control which could modify the gate length.

I am totally not a programmer. Is it trivial to make an analogue in pin accept a 0-5v cv to adjust pulse width?
Ie can I just cut n paste someone else's code?

I would be really interested in this, and as well on how to modify the code to be able to take CV inputs to modify parameters (density, length, offset)

Working build of the sequencer , testing to send voltage to a small DC motor with a piezo to get the sound of the vibration Very Happy

and a bit off topic, but the same idea with a baby8 sequencer too
