Driver for the Lectrobox DB-15 PC Joystick Shield.
The shield lets you attach any old-style PC joystick with a 15-pin game port interface to your Arduino. (USB joysticks are not supported.) The X and Y movement of the stick are returned in steps from -100 (fully up or left) to +100 (fully down or right). Your sketch can also detect button-pushes for up to two joystick buttons. Jumpers allow configuration of the Arduino pins used.
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
