Ok, so for the next version.


Pin 7s are  floating, tie to +5 if not used.
Are you sure you don't want to use Q7 of I.C. 2?  Edit maybe you want "see image"

Thanks for the tips. 

Should I connect the pin 7s to digital pins for versatility or is it worth it to use the pins.  Right now I just have pulled them high with the VCC out of the pro mini.

Thanks again!

If you have an free pin on the controller, route it to the outside of a three pin male header.
The other outside pin could be connected to +5V.
The middle pin of the header connects to pins #7.
Place a header jumper on the +5V or controller side as needed.
In the controller position, you can send a clear.

I'll bet you are getting comfortable with your schematic drawing program, that's the way you learn.
The way you have it in your schematic isn't the same as how you have it wired up!

You guys are brilliant!

I'll incorporate that.
