There are seven touch pads around the outside of the Circuit Playground Bluefruit, labeled A1 - A6 and TX. (A0 is not a touch pad!) This example plays a different tone and lights up the NeoPixels a different color for each touch pad touched.
Try touching the pads to hear a tone and see the NeoPixels light up. Touch each pad individually for one of seven different tones, and touch A6 and TX at the same time for the eighth tone.
