4. Usage
NOTE: Because each electrode needs to be auto-configured by the MPR121 when power up
and there is no power reset on the touch sensor controller, Every time you insert or extract a
feeler you need to reset the power of Seeeduino.
The feelers can also feel the human being fingers with something between, that's to say, you do
not need to touch the feelers with your fingers indeed.

With a paperboard about 3 mm thick, the feeler can feel the touch of fingers, makes it a good
solution for many applications.
