Moon light timer Answered

I would like to build a led light that switches on and off with the moon. On when the moon rises and off when the moon sets. Would also like no leds on at new moon and an additional led comes on until full moon is reached. The process then reverses an an led goes off until new moon with no leds on. I would also love the light output to be 4150k the colour of moon light and about 1 lumen at 1metre distance.

It will be difficult sensing these states of the moon and differentiating from the sun. Consider using a calendar and Real Time CLOCK to drive this. You could download astronomical tables off the internet, or calculate times yourself if you have the equations.
