Finally figured out the moon

I’ve been working on a GPS-controlled Arduino clock for some years and had set myself the goal of showing time for moonrise and for moonset for the present day. That turned out to be much harder than I had thought.

Finally, over the last few weeks I managed to adapt lunarCycle.c to Arduino and get it to work as shown in the display here. My ambition is now eventually to publish this project on GitHub as I’ve had several requests for it.

The display here shows local time and date, moon phase on line 2, present moon elevation and moon azimuth on line 3, and the next rise time of the moon and at which position on the final line. Follow label ‘Arduino clock’ below for more posts about this clock.
