Update to Version 0.6.2

A couple of changes in this update. We noticed a few minor display details that have been corrected in the code.

Also, after doing some additional testing we have decided to use a 9V battery to power the Arduino as opposed to the rechargeable in the original drawing. The other change is that we have added the resistor for the LED power lamp. That was missing in the original drawing as well. The drawing for the Nano version has been updated with both of these changes.
