Lately I have seen several discussions on pin debouncing in the Arduino forum. This made me lookup some of the existing solutions. Although some of them are very sophisticated I found that none of them will be suitable for my DCF77 clock project. The point is that I am going to put The Clock code into a library and then proceed to create a DCF77 alarm clock. Of course this will need pin debouncing. However because I have somewhat unusual timing requirements I want complete control on all interrupts and I do not want to rely on the Arduino’s millis() function. Thus I decided to implement my own debouncer.

In order to make it more accessible I decided to demo it with a simple one dimensional cursor effect.
