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 ‘ Multi-face GPS clock’ below for more posts about this clock.
