An accelerometer detects motion. More precisely, it measures acceleration in one or more of three directions which we call X, Y and Z. + +Using the Bluetooth accelerometer service you could, for example, create a smartphone application which makes a loud noise whenever your micro:bit (or the important thing you've attached it to) is moved. Or you could use your micro:bit to control the movement of a cartoon character in a game on your smartphone just by tilting the micro:bit in the direction you want the character to move in. + +No additional code is needed on the micro:bit to use the Bluetooth accelerometer service from another device. + +~~~~sig +bluetooth.startAccelerometerService(); +~~~~ + +### Example: Starting the Bluetooth accelerometer service + +The following code shows the Bluetooth accelerometer service being started: + +~~~~blocks +bluetooth.startAccelerometerService(); +~~~~ + +### Video - Accelerometer service demo - Starts at 0:18 + +[![micro:bit Bluetooth demo video](/static/bluetooth/microbit_accelerometer.png)]( + http://www.youtube.com/watch?v=aep_GVowKfs "Click to launch YouTube video" + ) + +### Advanced + +For more advanced information on the micro:bit Bluetooth accelerometer service including information on using a smartphone, see the [Lancaster University micro:bit runtime technical documentation](http://lancaster-university.github.io/microbit-docs/ble/accelerometer-service/) + +### See also + +[Bluetooth SIG](https://www.bluetooth.com) + +[Bluetooth on micro:bit resources](http://bluetooth-mdw.blogspot.co.uk/p/bbc-microbit.html) + diff --git a/docs/static/bluetooth/microbit_accelerometer.png b/docs/static/bluetooth/microbit_accelerometer.png new file mode 100755 index 00000000..47de394b Binary files /dev/null and b/docs/static/bluetooth/microbit_accelerometer.png differ
