B - Neopixel Grid

Neopixel Grid Activity

We are using the neopixel grid to display pollution levels below 2.5pm. The grid will light up each province in the country and represent levels of particulate matter with different colours.

Materials

Functionality

micro:bit A Button

• Cycle through the different programmed years.

• Each year is represented by a lit LED on the micro:bit.

• The data includes information from 1990 to 2014.

micro:bit B Button

• Goes back one year each time it is pressed, stopping in 1990.

Neopixel

• One of the rows of the neopixel will have lights representing the level of danger indicated by the particulate matter measurement. The colours are:

  • 🔴 red. high danger.
  • 🟡 yellow. Moderate danger
  • 🟢 green. Low danger
  • 🔵 blue. No danger
• The lights on the matrix will change each time buttons A or B are pressed, representing the air quality in each province that year.

• Once the project is assembled, the neopixel LEDs will light up points in each province on the map pre-printed on the cardstock sheet.
