Congratulations! You have learned how to program Adafruit’s Circuit Playground Express. Here are some of the things we learned:

  • Audio Output
cpx.play_tone(262, 1.0)
  • Capacitive Touches: cpx.touch_A1
  • Temperature Sensor: cpx.temperature
  • Light Sensor: cpx.light

Here is the Circuit Playground Cheatsheet.

Note: There are actually two ways to get audio output, one is via the small built-in speaker. The other is by using alligator clips to connect a headphone or powered speaker to the A0 pin!


If you are still feeling iffy about using the code, take a look at the Learn Python 3.
