Hi there,, i am trying to make a small slider using our skin based on resistance. and i find it hard to map the value.. it changes so abnormally.
i want to use my four fingers as touch sensors. i tried to analog read the different voltage level from it. and data is seriously randomous. based on sensor placement. :o :o :o help me please
The resistance of fingers varies with moisture and pressure. These are both widely variable. You will find on dry days, the R will be high. That may prevent sensing reliably.

so any solution?? i am ready to calibrate... i will use different logic level in each finger....
The R can change continuously simply by pressing slightly harder. The best you are lightly to achieve is contact or no contact.
