About RedBearLab BLE Nano Kit v2 - nRF52832

hi, i am wondering whether the RedBearLab BLE Nano Kit v2 - nRF52832 can measure the resistance variations of conductive fabric? can anyone help me with this?

Hi Yuan,
There are analogue input channels available in the GPIO, so the short answer is yes.
Perhaps the harder question to answer is how?
What are the properties of the conductive fabric you’re looking at? You’ll almost certainly have to develop some kind of measurement strategy or circuit for your application.

i want to use the redbearlab nano kit to measure the resistance changes and send the signals to a laptop. does it work in this simple way?

i am using Pressure-Sensitive Conductive Sheet (Velostat/Linqstat).

Hi Yuan,

That material changes resistance based upon the pressure applied to it. So you could use it as part of a simple voltage divider circuit, and use the corresponding change in voltage as a measurement for your application. There’s a stack of existing content out there on voltage dividers which you can draw upon, but they are just two resistors which create a reference voltage.
