Move the Dot

Challenge

The micro:bit boasts a vast range of on-board functionality. I’m sure you will have noticed the buttons and the LED matrix but may not have come across the accelerometer as of yet. You will have used this in the previous lesson as it is the component used for the shake function which was used in the previous ‘roll a dice’ lesson.

The challenge is to use the accelerometer to control the LED matrix and move a dot around the screen.

This challenge will give you the basis of understanding of how to use the accelerometer as a control input.

Additional Challenge

  • Think about how what you have learned can be used to create a simple chase the dot game?

Learning Points

  • Use the x and y axis of the accelerometer to control the LED matrix
  • Utilising variables to store and display numbers
  • Use the plot function for the LED matrix
  • Use IF statements to distinguish between the variable outcomes
  • Understand how the accelerometer can be used as a control input
