A - Neopixel Grid

Neopixel Grid Activity

In this activity we are using the 8x8 neopixel grid to visualize data from 3 different periods of time:

• Recent past(1976-2005)

• Immediate future ( 2021-2050)

• Near future (2051-2080)

We can also explore different carbon level scenarios, low carbon and high carbon, for the Immediate and Near future.

Functionality

micro:bit A Button

• Cycle through the three different time periods programmed.

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

micro:bit B Button

• Cycle through the three different years within the time period.

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

micro:bit A+B Buttons

• Toggle between low and high-carbon scenarios for the Immediate Future and the Near Future scenarios.

Neopixel

• One of the rows of the neopixel will have colour lights representing different temperatures.

  • Orange = very low.

  • Light blue = low.

  • Indigo = moderate.

  • Blue = high.

• The lights on the matrix will change each time buttons A, B or A+B are pressed, representing the precipitation level 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.

We continue with our rainy weather in the next section, this time we are working with the servo motor.
