BBC micro:bit – Automated Car Park Display

car-park-signOur aim is to use the BBC micro:bit to create an automated Car Park Display to inform drivers of the number of empty spaces left in a car park.

Our system should:

  • Be initialised with the number of available spaces in the car park set to 20 and the car park will be empty when the program is started.
  • When the car park is empty the micro:bit should display a scrolling message saying “Car park is empty”
  • car-park-empty

  • To enter the car park, the driver has to press the A button of the micro:bit. The display should then changes to calculate and display the number of empty spaces left: e.g. Scrolling text : “15 spaces left”.
  • car-park-15-spaces-left

  • When a car leaves the car park, they will press the B button of the micro:bit. The display should then changes to refresh the number of empty spaces left.
  • If the car park is full, the micro:bit should display the scrolling text: “No entry – Car park is full”. Drivers should not be able to enter the car park. Instead, should the A button be pressed the display should say “No entry – Car park is full”.
  • car-park-no-entry
