1  Using Arduino / LEDs and Multiplexing / Re: Using MAX7219 and MXA002 LED Seven-Segment on: Today at 12:52:48 pm
I would use SPI.  10, 11  and 13
You need the ground of the 12 V supply connected to the ground on the Arduino.
Your Arduino needs 5V not 6 V !

Looks like the start of your own HOLODECK.
3  Using Arduino / Interfacing w/ Software on the Computer / Re: Terminal Program for Windows 8 on: July 24, 2014, 12:24:02 am
I have used Realterm on Windows 7, I believe it will work on 8.

Bob has it.
Zoom in and you will see the traces going to the headers.

Yes
They are probably connected on the underside.

I want to avoid using wires to connect to the digital pins and want to simply solder my connections to them. 
You do have to solder wires to the pads that are labeled eg. A0, then to any components that are mounted on the board.

7  Using Arduino / General Electronics / Re: What's this peice called? on: July 23, 2014, 10:47:56 pm
Drawing too much current, blame the operator smiley-wink

Maybe put one of these on the regulator.

What is it you are trying to do?

12  Using Arduino / Project Guidance / Re: Battery monitoring for Arduino UNO on: July 22, 2014, 08:24:22 pm
What kind of battery do you need to monitor?
Try:
Google    arduino battery monitor
13  Using Arduino / Project Guidance / Re: Problem with max7219 ! on: July 21, 2014, 12:39:57 pm
Move your +5 and GND wires  (the ones from the arduino) to the far left side of your breadboard power buses.
Some bread boards have a break half way down the  power rails.
It might be your grounds aren't really there because of the above situation.
14  Using Arduino / Project Guidance / Re: Problem with max7219 ! on: July 20, 2014, 11:20:17 pm
I loaded your code and it works fine.
What is the voltage from pin 19 to 4?
15  Using Arduino / Microcontrollers / Re: New Mega2560 Layout on: July 20, 2014, 09:48:40 pm
This is kind of interesting might be able to get some ideas here.
