## Accelerometer, gravity and tilting!
The micro:bit contains an **accelerometer** sensor that is able to measure forces applied to the board.
The @boardname@ contains an **accelerometer** sensor that is able to measure forces applied to the board.
On earth, we are subject to the **gravity force** which pulls us to the ground!

When the micro:bit is flat on a table, with the screen pointing up, the gravity force is aligned
with the **Z** axis of the micro:bit.

If you tilt it up and down, the force will align with the **Y** axis -- this is how we can detect tilting!!!
If the force along **Y** grows, the micro:bit is tilting more and more vertically!
