Once your tree is assembled and your code has been uploaded, it's time to switch between animations. This is done using the Adafruit Bluefruit LE Connect app.
Once you connect to the Circuit Playground Bluefruit, select the "Controller" option; followed by "Control Pad". This then brings you to a screen with 8 buttons. As we went over in the code, the up, left, right, down, 1, 2 and 3 buttons will all trigger different animations and 4 will turn off all of the NeoPixels.
