WorldClock

This is a WorldClock implementation using Atmega 328 and DS1307 as a RTC.

Inspiration

This project was inspired by this instructable that relies on a DS1302 instead of a DS1307. A couple of changes had to be made since these clocks work in different ways (DS1302 Datasheet and DS1307 Datasheet).

How To

• Get all the parts necessary according to the Bill of Materials in Part 8 of the instructable linked above (for electronics you may use the schematic if you prefer)

• Etch the PCB using your favorite method or using a service like OSH Park

• Flash the program into your Atmega 328 using your programmer of choice

• Solder every component into your PCB

• Test it out

• Follow the instructions linked above in order to build the clock's enclosure

• Put everything together

• Enjoy!
