Hello! Iβve created a simple joystick project for smartphones. The purpose of creating this project is to help the community in dealing with smartphone controls. Everyone is free to use, modify, and improve the example project and of course, its still not in a great shape, but with further improvements, it would be awesome .
Example #1
Example #2
