Circuit 2
In this circuit, we are going to use yet another kind of
variable resistor – this time, a soft potentiometer (or
soft pot). This is a thin and flexible strip that can
detect where pressure is being applied. By pressing
down on various parts of the strip, you can vary the
resistance from 100 to 10K ohms. You can use this
ability to track movement on the soft pot, or simply
as a button. In this circuit, we’ll get the soft pot up
and running to control an RGB LED.
