Arduino-based master clock for schools

Step 5The Arduino firmware

The Arduino firmware
Load the "Master Clock Firmware" Arduino sketch into the Arduino IDE.

You will also need to install a number of other libraries (if you do not have them installed yet)
* DateTime (use the modified version attached here)
* DaylightSavings (see the next step)
* DateTimeStrings
* Flash
* Streaming
* LiquidCrystal (comes with IDE)

The libraries together with the code makes the sketch too large to fit in a Arduino ATmega128, which is why an '328 is needed. Perhaps if you remove some code that you do not need for your project it can fit.
