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.

Servo Motor

• It will move each time either the A or B buttons are pressed on the micro:bit to the specified pm reading for that year.

• Once the project is assembled, the servo motor will point to the scale drawn on the cardstock sheet.
