Simplest Arduino to Axoloti method (CV or Serial or midi)


#1

Hi,

Quick version :
What is the easiest way to convert a float variable in arduino nano to micro tonal pitch in Axoloti (like the hakken continuum or a theremin) ?

Strange version :
First I saw the multiple discussion on arduino to axoloti and they all try to achieve fairly complex connection (for me, as a beginner in all this) i'm looking for something simpler since it 's my first project with both.

I have an arduino NANO which for the moment print the variable i want in the consol/monitor of the IDE. It's a FLOAT variable that change over time I want to convert it to pitch (or something else but pitch is a good place start). It would sound like a theremin or a ribbon synth since I don't want to map the value to notes.

First I didn't want to use Midi because i felt it would be realy hard to code a continuum and not outpout do do# re re# mi etc.
Then I tried going through CV (or analog input on the axoloti) but I need a DAC and it's quite a bit of world I don't fully understand (I tried with a resitor and a capacitor on a microbrute CV IN and with random inputs on axoloti : didn't work, that PWM output of the arduinos analogWrite is quite not as cool as it sound).
Their is the serial which seems quite easy on the hardware side but I don't know C.
So the 3 options are pretty attractive to me but since I'm new to this I don't know which one would be the fastest path to control the pitch of axoloti with arduino.
Thanks

If I were doing this, I would convert the float to a suitable range of ints (say 0-255 mapped for 8 bit) and then send it out on 8 pins to the axoloti, which would then read those 8 pin values to a 0-255 number. Seems a bit convoluted and not as elegant, but that's my two cents.
