Objectives

  • learn how to repeat code in the background forever
  • learn how to get the acceleration value (g-force), in one of three specified dimensions
  • learn how to display a vertical bar graph based on the value and high value.
  • learn how to register code to run when a packet is received over radio
  • learn how to broadcast a number data packet to other micro:bits connected via radio
  • learn how to read the next radio packet as a number data packet
