Practice Exercise: Ambient Calendar Alert

The final practice exercise needs to combine neopixel with IFTTT. My IFTTT set up is as follows:

When any google calendar is 15 minutes away, call the Particle.function with the input of time duration of the alert. For simplicity of the demonstration, the time duration of each phase is set as only 1 minute.

The three phases of the alerts are inline with the advanced requirement on the course website:

1. 15 minutes before the calendar event starts, the ambient alert will begin displaying.
2. It will fade up slowly for 10 minutes to solid white
3. 5 minutes before the meeting, the color will begin to slowly change from white to red over those 5 minutes.
4. At the time when the meeting takes place, the ambient display will present as red
5. Then it will slowly fade out over 5 more minutes.
