+// This application displays data from the old Sensor Watch Motion sensor board.
+// Note that this board required A0 to be set high to power the sensor.
+// Future accelerometer boards will be powered directly from VCC.
+// Also note that this board has its INT1 pin wired to A1, which is not an external
+// wake pin. Future accelerometer boards will wire interrupt pins to A2 and A4.
