Sample#

Remote Control Part#

  • Set the micro:bit showing a set icon and the radio group as 1.

  • Radio send x which is given by its acceleration dividing 10 in the forever brick.

  • Radio send y which is given by its acceleration dividing 10 in the forever brick.

Receiving Part#

  • Set the micro:bit showing a set icon and the radio group as 1.

  • Drag two” if…else…” sentences to the “on radio received…” block, judge if the received name is x or y.

  • If it’s x, save it as the variable as the accelaration from the x.

  • If it’s y, save it as the variable as the accelaration from the y.

  • Set the speed of the left wheel being y+x and the right wheel being y-x.
