Test the System!

Open the terminal window, navigate to the folder where you saved the program code using the cd command.

cd path/to/folder

Run the program using root privileges:

sudo python NameOfFile.py

Check that the acceleration values in the x, y, and z-direction are printing to the terminal window, are reasonable, and turn on the LED light if the g-force is above our thresholds.

• To test, rotate the accelerometer so that the each axes point towards the earth and check that the measured values are either 1 or -1 (corresponds to acceleration due to gravity).

• Shake the accelerometer to make sure the readings increase (sign indicates direction of axis, we're most interested in the magnitude of the reading).
