G-Force meter for resistence testing on machine, save data in card microSD in the format CSV.
This project used an accelerometer as sensor to g-force meter, in most cases the acceleration is used as a vector quantity, which can be used to sense the orientation of the device, more precisely pitch and roll. Because when you turn the device, the 1G component is distributed among those 3 axes. With simple vector math we can calculate the angle of the device.
