Observations

In the Simple Counter activity, students will see:

Each time they press the A button on the micro:bit, the number will increase
by 1.

The micro:bit will show the updated number on its screen.

Students will learn how to create a simple
counting system using coding.

Application

Pedometer: It counts the number of steps

you take each day. Each time you take a step,
the counter adds one to the total. By the end
of the day, you can see how many steps you

have walked.

Building a Direction Blinking Arrow

The Micro:bit has a variety of sensors. One of
these sensors includes an accelerometer. The

accelerometer is behind the B- button. A label
on the micro:bit behind the button’s points

to the motion sensor. The accelerometer
measures motion. The motion comes from
lifting or rotating the Micro:bit.

The accelerometer measures motion in three

different directions. It measures motion when
the Micro:bit is moved side to side or up and
down.

The micro:bit measures movement along three axes:

X - Tilting from left to right.

Y - Tilting forwards and backwards.

Z - Moving up and down.
