charting lesson

Create a charting app for simulating and measuring the acceleration applied to the micro:bit

Topic

Acceleration

Quick Links

Prior learning/place of lesson in scheme of work

Learn the functions of on data received, send number and receive number and chart plot bar graph for acceleration in the "x" dimension.

Documentation

input.acceleration(Dimension.X)
led.plotBarGraph(0, 1023)
basic.showNumber(0)
radio.onDataReceived(() => {})
radio.sendNumber(0)
radio.receiveNumber()

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
