module's UART line with 38400 bps baudrate mode, 8 bits data,1 stop bit, and without parity.

8. Spin the DT-SENSE 3 AXIS GYROSCOPE module to test the changes on each of the gyroscope's axis.

9. If the DT-SENSE 3 AXIS GYROSCOPE module is spun with Z axis shaft (shaking motion), then the gyroZ value will change the most.

10. If the DT-SENSE 3 AXIS GYROSCOPE module is spun with X axis shaft (nodding motion), then the gyroX value will change the most.

11. If the DT-SENSE 3 AXIS GYROSCOPE module is spun with Y axis shaft (teeter totter motion), then the gyroY value will change the most.
