Yet another Arduino clock
Does the world need more Arduino clocks? Maybe not. But I needed another Arduino project as I had made a K3NG morse keyer. I love this keyer because it is unique in supporting a display where you can see what you send.
But I wasn’t using the morse keyer all the time, so I wanted the hardware to serve two purposes. That’s the excuse for also making a clock. Its main features are:
- Controlled by a GPS module outputting data over an RS232 serial interface, and handled with the TinyGPS++ library
- Shows raw GPS data such as UTC time and date, position, altitude, and number of satellitess
- Shows derived GPS data such as 6-digit locator
- Finds local time and handles daylight saving automatically using the Timezone library
- Finds local sunset and sunrise, either actual value, or civil, nautical, or astronomical. The library is Sunrise.
- The clock also gives local solar height based on the Sunpos library from the K3NG rotator controller.
- Finally, the clock also provides the lunar phase based on ideas found here and using a reference new moon on 11 November 2015, 11:47 (UNIX time 1447264020)
UTC and position display Line 1: UTC time, locator Line 3: latitude, longitude Line 4: Altitude, number of GPS satellites |
Dual time display with local time, UTC time, and locator |
