A/B Buttons:
There are
two buttons
on the front of the
micro:bit - button A and button B, you can detect when these
buttons are pressed, allowing you to trigger code on the
device. You can detect events such as a single press, a double
press, and a long press by programming.
Light Sensor:
The LED screen works as a basic
light sensor
by
reversing the LEDs of the screen to become an input which
allows you to detect the ambient light.

Temperature Sensor:
The Microcontroller
doubles
as a temperature sensor
! The temperature sensor
transforms the temperature in the ambient
environment into digital signals that can be read by
the micro:bit for calculating the current tempera-
ture of the device.
Compass:
The
compass
detects the earth’ s magnetic field,
allowing you to detect which direction the micro:bit is facing.
The compass has to be calibrated before it can be used.
Calibrating the compass ensures the compass results are
accurate.
Accelerometer:
The accelerometer
measures
the acceleration of your micro:bit
, it can track
motions like tilt, free fall and shake.
