Neopixel Ring

We are using the neopixel ring to display the past, present and future annual mean temperatures in Canada.

Materials

Assembly Instructions

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 time periods are:

  • Recent Past.

  • Immediate Future.

  • Near Future.

micro:bit B Button

• Cycle through 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-temperature scenarios for Period 2 and Period 3.

Neopixel Ring

• LEDs on the ring represent:

  • The top part of the ring represents the different provinces

  • The bottom part of the ring represents three different messages:

    • 🔵 Blue = safe

    • 🟠 Orange = caution

    • 🔴 Red = danger

All this talk about temperature is making us feel hot. In the next section, we tackle a topic that may help us cool down, Precipitation.

Description

This activity is a direct connection to the concept we explored in theShowcase Projects section. Specifically when we went over the IPCC Global temperature scenarios. As we discuss in that section, this type of visualization invites us all to be active in helping reduce the effects of climate change.

We have two different activities, each one using a different tool. One of them uses the neopixel in the shape of a grid and the other one in the shape of a ring.

Let's get started in the next section, with the Neopixel Grid and different Climate Scenarios.

Neopixel Grid Activity

We are using the neopixel grid to display the past, present and future annual mean temperatures in Canada.

Materials

Assembly Instructions

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.

In the next section, we this same topic, but this time using a neopixel ring.
