Acc 06: 6D Movement

This example shows how to manage the 6D Movement recognition interruption.

Required Materials

1 x Waspmote 1 x MiniUSB wire

Notes

- When the 6D movement interrupt is activated, a change in the movement of Waspmote will generate an interruption and wake up Waspmote. - This example can be executed in Waspmote v12 and Waspmote v15
