Parts Ordered

I have ordered my parts, and they should be here in about a week.  Hopefully i have ordered everything I need, and do not need more. The instructable I found, which my project is based on, has these parts:

1 LTC-617 clock display

1 Arduino (I used an Arduino-nano)

many jumper wires

1 button

1 resistor: 10k or close (to prevent short between gnd and 5v on button press)

but I thought it would be better if I used LED lights to create my clock so I have ordered those as well. The kit I ordered does not have the LTC clock display, but it does have a display that hopefully will work.
