Check out also pd-l2ork k12 documentation where you can learn more about "lots of pots"  RPi shield that gives you essentially 8 capacitive channels via the aforesaid mcp3008 d/a chip. This is what pd-l2ork essentially supports out of box.

To access k12 mode start it with appropriate shortcut or simply type pd-l2ork -k12

Thanks Ivica,

I'll check out pd-l2ork. I might use a Raspberry Pi for that purpose anyway.
I need some capacitive sensors that work without actually touching them. All
I found was using I2C.

I forget what i2c uses driverwise, but if it is spidev, in pd-l2ork you have
disis_spi external that allows for reading data from mcp3008 8-channel ad
converter. The external is specifically designed for Raspberry Pi build of
pd-l2ork, but I don't see a reason why it could not be compiled for vanilla
Pd as well. Perhaps it can be also used with your setup?

Could be a possibility but I was hoping for an object that would be able to
read I2C directly without adding an arduino since most smaller arm boards do
have some I2C pins onboard.

What if you use the Wire library in Arduino and then collect the info in Pd
with [comport]?

I have been using an arduino with [comport] (pduino) to read out sensors so
far and want to use a I2C sensor board for some other sensors soon.

Can [comport] connect to the I2C interface or is there another object in
Pd-extended that can do that?

Thanks!
