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.

• The set time periods are 1976-2005, 2021-2050 and 2051-2080.

micro:bit B Button

• Cycle through the three different programmed years.

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

• The set years for each time period are:

  • Period 1 (1976-2005) includes data for the years 1980, 1990 and 2005.

  • Period 2 (2021-2050) includes data for the years 2030, 2040 and 2050.

  • Period 3 (2051-2080) includes data for the years 2060, 2070 and 2080.

micro:bit A+B Buttons

• Toggle between low and high-temperature scenarios for Period 2 and Period 3.

Neopixel

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

  • 🔵 blue - Low mean temperature. Below or equal to 9ºC.

  • 🟣 purple - Medium mean temperature. Between 9ºC and 12ºC.

  • 🟡 yellow - High mean temperature. Between 13ºC and 15ºC.

  • 🔴 red - Very Hight mean temperature. Above 15ºC.

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