- RTClib - https://github.com/maniacbug/RTClib
- SerialDisplay - Something I wrote. I will upload it soon.
A DeadOn RTC from sparkfun (DS3234 chip). Communicating over SPI.
A 4 digit 7 secment display from sparkfun. Also using SPI (not serial).
A "buzzer" that is really just a small speaker.
An Arduino ofcourse (I used the Nano V3).
3 Buttons. One large one and two smaller ones.
And a resistor network to pull down the button pins.
I purchased all my components from Little Bird Electronics in Australia. http://littlebirdelectronics.com/
