Now touch the pin indicated in the diagram above. You'll see
to the serial console!
First you
import
modules available for use in your code. All three are built-in to CircuitPython, so you
don't find any library files in the Project Bundle.
Next, you create the
the module. You save that to the
board
Inside the loop, you check to see if the pin is touched. If so, you print to the serial
console. Finally, you include a
readable.
That's all there is to reading touch on a single pin using
Multiple Capacitive Touch Pins
The next example shows you how to read touches on multiple pins in a single
program.
