This is a clock designed to keep accurate time (independent of atomic or GPS), display local sunrise, sunset and solar noon, and also adjust itself fo...
As stated in the intro, I wanted the clock to be easy to use, accurate, simple but also flexible. Easy to use: - menu-driven setting options - digit-...
As mentioned before, I went with the Arduino platform - not so much for the Arduino-branded hardware but mostly because I've done a number of projects...
The first thing I developed with the menu and setting system. Creating the menus is easy - just increment or decrement an array index and then read th...
A number of values in the clock need to be stored in EEPROM. Some, like the display schedule, are fine as bytes. Others, however, need a signed float....
This is where libraries are great. I used Timelord.h and formatted my data into the array it expected and get back all my solar and lunar data. Only o...
This one was easy. Just search the 'net for how to talk to a DS1370 - they're the same. I had to do a bit of digging on how to enable and set the SQW ...
I got the concept for doing the big numbers from another project online. It's clever - you create an array of your custom characters, including a lead...
The case I chose has a number of screw mount points inside the chassis. Unfortunately, none of them are really where I need them. I needed the VFD a c...
The code for the clock is at GitHub: https://github.com/quarterturn/Solar-Oriented-Clock Version 1.3 used Button.h Version 1.4 uses Bounce.h
