# B - Neopixel Fairy Lights

### Neopixel Fairy LightsActivity

In this activity we are neopixel fairy lights to visualize carbon dioxide emissions from each province from 2009 to 2019:

### **Functionality**

#### **micro:bit A Button**

* Move forward to different years from 2009 to 2019.
* Each year is represented by a lit LED on the micro:bit.

#### micro:bit B Button

* Move back to different years from 2009 to 2019.
* Each year is represented by a lit LED on the micro:bit.

#### Neopixel Fairy Lights

* One of the rows of the neopixel has colour lights representing different levels.
  * 🟢 green - Safe.
  * :yellow\_circle: yellow - Caution.
  * :red\_circle: red - Danger.
* Provinces location on the Fairy Light from left to right:  Ontario, Saskatchewan, Yukon, Quebec, Manitoba, British Columbia, Alberta, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, PEI, Nunavut.
