You’ve already bored with the old-fashioned clock, but you think it’s unnecessary to spend the money buying a new digital clock, especially in this economic turbulence period?

Well, if you’re really want to own a digital clock, then why don’t you spare a few hours and develop a sophisticated time display unit?

Unlike the other time display, this one is slightly different, as it has a PIC18F1320 microcontroller for experimentation and installed with a cheap GPS module!

Below here are some of the unique features of this time display:

1. UTC time configurable (It’s for differencing time zones with DST option).

2. Super low power consumption.

3. Two difference time display modes (12 or 24 hour).

4. A leading zero blanking option.

5. AM/PM indication (Only available in 12 hour mode).

6. GGA and RMC sentence status indication.

For your information, this project requires the use of on-chip 8 Mhz oscillator, which is driving a six digit LED display. If you prefer a brighter and better display, you would like to consider applying a MAX6951 chip into the project.

By the way, the MAX7219 display driver is another great option for this project, as the chip has an option to adjust the display brightness easily!
