Hello Circuit Playground

A set of very basic example sketches to demonstrate the various components of the Circuit Playground. These sketches were tested and verified with:

  • Circuit Playground Developer Edition
  • Ubuntu 16.04 LTS
  • Arduino IDE 1.6.11
  • Adafruit AVR Boards 1.4.9
  • Adafruit Circuit Playground Library 1.6.1

Hello_Blink

Blinks the little red LED next to the micro USB connector once per second.

Hello_SlideSwitch

The position (+ or -) of the slide switch is sent to the serial monitor once per second.

Slide Switch: -
Slide Switch: +
Slide Switch: +

Hello_Buttons

The position (UP or DOWN) of the two push buttons are sent to the serial monitor once per second.

Left Button:   UP   Right Button:   UP
Left Button: DOWN   Right Button:   UP
Left Button:   UP   Right Button:   UP
Left Button:   UP   Right Button: DOWN

Hello_LightSensor

The reading (0-1023) from the light sensor is sent to the serial monitor once per second.

Hello_Speaker

Plays a 500Hz tone for 0.1 seconds on the speaker, followed by 1 second of silence.

Hello_NeoPixels

Clears all pixels for 0.5 seconds then displays colors on the fist 5 pixels using individual 8-bit values and the same colors on the next 5 pixels using 24-bit values. After 5 seconds, this repeats.
