The accelerometer is one kind of event that is considered as a no-touch event because it has neither start nor an end, it is always providing information.
In this recipe, we will use the Kv language for the design of the widgets, so, again, you will need to be familiar with the Kv language. Also, this recipe will use the common button and label widgets for reference. Obviously, to get more benefit, a device with an accelerometer is useful to run the code.
It is necessary to install a package for the use of the accelerometer in any mobile device; there is a way to deal with every specific device, but we do not have to reinvent the wheel. Let's use a Plyer package, which is an effort from many of the Kivy developers. To install the package from the shell, use:
