How to draw current from one VDD(A) multiple times?

#1

Hey community,
first of all: please have mercy with me, since I am completely new to this technical world of music :slight_smile:
And unfortunately I couldn't find an appropriate answer in forum...

How do I technically solder multiple potentiometers to the board?

I am not talking about "how to hold a soldering bolt", but in the sense of how to use one VDD(A) multiple times. There are much more inputs (PA1-C5, etc.) than there are grounds and vdd(a)s. So how can I apply multiple pots correctly? Is there some sort of bridge or cable multiplier that I could use?

If possible give me an exact example like:
Listen you dumbxss... Solder the minus to the ground, the plus to the VDDA and the middle to PA1. :wink:

You know, where I am going with this :slight_smile:

And is it technically okay to use one VDD(A) multiple times or could this overload the current supply?

Please help,
Greetings
Marvin

H.

you do the same way you would do with an arduino or whatever..

if you are going to connect 8 pots, for instance, you wire together all the grounds, then all the Vdd pins and then you just connect 1 cable from the poti grounds to one axoloti Gnd. another cable from the vcc's to Axo Vcc and then, the independent sensor / potmeter outs to its respective inputs. Here I have a graphic I made for another thing but you might get the idea..

Hey, thx a lot! That was exactly, what I was trying to find out! :slight_smile: Do I also have to use these 10k resistors, when I wire my pots that way?

Hi, you welcome.
nope, the 10k resistors are used to implement Light resistors as sensors or other kind of sensors with 2 legs (force resistors, bending resistors..)

I understand, thank you for the info. I don't want to overload you, but could I also use that technique with buttons? I mean: Does this in a row wiring works for buttons on the vdd(a) and PA-C as well?

buttons just need ground but yes, you can join the ground "common rail" and then connect their respective outputs to the digital pins of your choice
