the microbit machine learning tool lets
you train test and improve a machine
learning model that can recognize
different actions or
movements here's a quick tour of how it
works you'll need two microbits you'll
hold or wear the first
microbit follow the instructions on
screen for setting up microbit
one then unplug it and attach a battery
pack if you have a wrist strap you can
attach microbit one to your
arm the second microbit stays connected
to your computer with a USB cable follow
the instructions on screen for setting
up microbit
2 at the bottom of the screen you'll see
live movement data from microbit 1's
accelerometer
sensor each colored line represents a
different direction or Dimension you're
moving the microbit
in Step One add some
data decide which actions you want the
microbit machine learning tool to
recognize clapping and waving are good
ones to start
with name your first action then start
moving click the red button to collect
your first sample of
data collect at least three samples of
your first action
and do the same for at least one other
action step two train the model this
means that the machine learning tool
makes a set of rules to estimate which
action you're doing when moving microbit
one step three test the model try making
each of your actions the screen shows
which action the model estimates that
you're making the percentage number is
how confident or sure the model
is now try it yourself and see what
different movements you can train the
microbit machine learning tool to
recognize
