Arduino OneButton Library

This Arduino libary is improving the usage of a singe button for input. It shows how to use an digital input pin with a single pushbutton attached for detecting some of the typical button press events like single clicks, double clicks and long-time pressing. This enables you to reuse the same button for multiple functions and lowers the hardware invests.

This is also a sample for implementing simple finite-state machines by using the simple pattern above.
