10. Accelerometer
On board
measure acceleration in three axis: x, y and z. The
accelerometer’s function is defined by the user in the
program loaded into the microcontroller. Communication
between the accelerometer and the microcontroller is performed
via the

You can set the accelerometer
address to 0 or 1 by re-soldering the
SMD jumper (zero-ohm resistor) to the
appropriate position. Jumper is placed
in address 1 position by default.
