Multiple potentiometer circuit diagram

Can someone please confirm if this is ideal.

Hi Sahaj,

Hi Sahaj,

What is the softpot component? If its a normal 10 potentiometer you wont need inline resistors.
It might be worth reading though some electrical engineering basics, was there a guide you are following?

Softpot is one of these:

Im just following a number of snippets from web like this one: https://www.youtube.com/watch?v=cng0MI5YCr0
According to https://www.adafruit.com/product/178 it does need multiple resistors to avoid burns and being extra careful

Thereâ€™s not much on connecting multiple potentiometers around.

Hi Sahaj,

Then in that case it looks alright.

Connecting multiple is no different to connecting one, youâ€™ll just have to use a different analog in pin.

Hi Sahaj
The two soft pots in the top are not going to do much, everything is going to ground.

I see yes i think second configuration should be ok

Hi Liam
If you look closely you will see there are no â€śin lineâ€ť resistors to Arduino inputs. They are everywhere else though.
There is 1 common 10k from 5V to the â€śtopâ€ť of all pots.
There is a 10k from the â€śbottomâ€ť of each pot to ground.
There is a 10k from the â€śoutputâ€ť of each pot to ground.

This is effectively having the pot operate over 33% of the 5V about the centre. ie from 33.3% to 66.6% of the 5V.

To complicate this there is that 10k from each output to ground so as this is effectively in parallel with the 10k resistor plus what is left of the pot what you eventually end up with would be anybodyâ€™s guess. Could be calculated of course but you can do that, I am not going to bother
