Using the Alarm

Once the sketch has been loaded on the Circuit Playground, it is ready for use. Install the batteries, plug in the power cable, and turn the switch on. You should see all of the NeoPixels come on and turn red.

All the lights are on. Ready to use.

Press either button to start the countdown timer.

The NeoPixels will turn off one at a time.

BEFORE ALL THE LIGHTS GO OUT, PLACE THE DIARY ON THE CIRCUIT PLAYGROUND.

Make sure the diary covers the light sensor before the countdown ends.

When the countdown ends a short BEEP will sound.

If you now remove the diary from the Circuit Playground, the alarm should sound. You can press the RESET button to stop the alarm and start again. Yes, this is an easy way to defeat the alarm, but hopefully you will hear the alarm before someone figures that out.
