« A sensor is a special electronic part that can detect changes such
as movement, light, sound, direction or temperature.
« Sensors can detect movement, direction, temperature, light and more.
« The Micro:bit also has built-in sensors that allow it to do similar things.
« The Micro:bit can sense movement through its motion sensor, also known as the
accelerometer.
« The accelerometer measures movement in three directions: side to side, up and down,
and forwards and backwards.
« The Micro:bit can show a visual indicator like an arrow pointing to the current direction.
« The accelerometer measures movement in three directions: side to side, up and down,
and forwards and backwards
« The compass sensor is a great way to explore how real-world navigation systems work.
Exercise
