Arduino Project Notes
These are project notes pertaining to the variety of Arduino "Sketches"
UNO Configuration
(The wiring interface is identical.)
The primary differences between the "Arduino UNO Configuration" used with a UNO device, and "Arduino UNO Configuration" used with a MEGA device, is the potential allowance of additional Analog and Data Pins available on the MEGA. Otherwise, only the download parameters are different, but the behavior and LCD display remains identical.
You will need to wire all the required connections between the UNO or Mega and the 2x16 or 4x20 parallel LCD, unless you have a custom interface board available. I find having this board available allows me to quickly switch between various devices, and was well worth the expense.

MEGA END Configuration
(Where the Parallel LCD is either plugged directly into the Even-Numbered-Pins at the end of the Mega, or wired accordingly)
This method allows use of the Analog Pins and the other Digital Pins for other considerations. With some blue background LCDs, it may be necessary to add a contrast control. Here again, you will need to wire all the required connections between the UNO or Mega and the 2x16 or 4x20 parallel LCD, unless you have a custom interface board available. I find having this board available allows me to quickly switch between various devices, and was well worth the expense. I plan to publish all the ExpressPCB layouts for everyone, here on my website.
