Word Clock Sanity Check

Using Arduino Project Guidance
1

Hey all,

I am building a word clock based on scottbez's instructable, and since this is my first electronics project ever I thought I'd post some pictures to make sure I'm not missing anything super obvious.

This is a link to the album I have of it mostly breadboarded, I don't have the power supply hooked up yet nor is it attached to the LED's.

I used a combination of the hand-drawn sketch on this http://www.instructables.com/id/Sleek-word-clock/step7/Wiring-up-the-Arduino/ page and the schematic from this http://www.instructables.com/id/The-Word-Clock-Arduino-version/step1/The-new-hardware-Controller-board-schematic/ page.

A couple specific questions I have are:

On the ATMEga328 what am I supposed to be doing with pin 1?
In scottbez's example he only has 1 100uf capacitor, most arduino on breadboards have 2, are they both necessary?

in drj113's schematic pin 9 on the uln2003a's says common, its blank on scottbez's example. Does it need hooked to anything?
Another difference is on the connection from one hc4094 to the next, is it on pin 9 or 10 (Bottom right or second from bottom right?)
In socttbez's example, do I Tie all the OE pins from all the HC4094's to pin 15 on the Atmega328?

Thanks!

Assuming your referring to this schematic then pin 1 is tied through a 10K resistor to 5V.

You should have decoupling capacitors on the power rails to all the chips. The voltage regulator would also normally have 2 capacitors (check your components datasheet to be sure)

You really need to decide what version your going to follow and stick with that as the code/design may not be interchangeable.

Here is another method for a wordclock. It was the first arduino project I made so could probably be improved as this was the first C++ code I wrote but the two clocks I built are still going strong. I'm slowly gathering the parts to make a colour version with 256 LED's.
