Arduino Sunrise Sunset Library

Here’s an arduino library to calculate sunrise and sunset times based on date and latitude / longitude, i didn’t made the library, i took it from this website that doesn’t seem to work anymore: http://www.swfltek.com/arduino/sunrise
I’d like to give credit to the one who wrote it but i couldn’t find a creator name or contact anywhere!
i used it for my new “PS. I Love You” piece and incorporated a Noon function which returns the time when the sun is in mid sky.
Example included.

thanks Michael for your comment!
so full credits of the library goes to Michael Rice
and here’s the working link that i thought it was broken:

    Thanks André, I’ll give it a go. By the way:

    Time of noon was a clever mod!

    The original is still there, you just dropped the ‘.html’ off the end of the url.

    Since then I have rolled the SunRise library into a more expansive ‘TimeLord’ library, and with your permission I will include your noontime mod (with due credit of course).
