The code for this project is a fork from the original TIMESQUARE project. It adds an additional wordclock mode to the existing display modes.
You can download the code from github here: https://github.com/andydoro/Wordclock-Wristwatch
Follow the directions in this guide to upload new firmware to your TIMESQUARE wristwatch.
Open the WordclockWatch.ino sketch in your Arduino IDE.
You will need an FTDI cable or FTDI friend. Make sure to have the FTDI cable or friend oriented correctly! The FTDI cable works best with some extra long 6-pin headers. You should be able to "press fit" the FTDI cable or FTDI friend pins into the holes so you don't have to solder them in.
Select Lilypad Arduino w/ ATmega328 as the "board" type.
You should be able to use the TIMESQUARE watch as before, except there will be a new Wordclock Mode between "Moon Phase" and "Battery Gauge"
The new sequence will be:
↪Marquee↔Binary↔Moon Phase↔Wordclock↔Battery Gauge↩
As with the other display modes, Wordclock mode will display for a few seconds after you tap one of the side buttons- after you've attached the faceplate, of course!
