Is there any limit to the size of surface that can be used for capacitive sensing using toughRead on a Teensy3.2?
I did some successful testing with a sheet of copper about a square foot that worked but now am having some problems using four new sensors (on four pins).
Could I run into limits for current capacity for charging, or time to charge limits?
