There are seven capacitive touch pads and ten NeoPixel LEDs on your Circuit Playground Bluefruit. The touch pads are labeled A1-A6, and TX. A0 is not a touch pad. This example uses the touch pads to light up the LEDs in rainbow colors.
Try touching different touch pads to light up the LEDs as different colors of the rainbow.
