// An example sketch using the joystick library, demonstrating multiplexer support
// In this example, we have 21 buttons we want to attach.
// Unfortunately, the Arduino Uno only has 17 pins we can use!
// So we've added an 8-channel multiplexer, connected to pins A1-A5.
//
// Note: this may not be the best approach for this many simple buttons. Using an input matrix
// would require as few as 10 inputs in this scenario, for example. This is just a demo :)
#include <Joystick.h>
#include <Mux.h>
