Building an Arduino LCD Interface, Part II

Continuing with the Building an Arduino LCD Interface series, this post will focus on creating the LCD panel schematic in Eagle.

With only a small amount of components, building the LCD panel schematic was a quick process.  I already knew that I wanted to connect the panel via some custom wires (more on that in a later post), so most of the board consists of 0.1" headers.  The only piece not already in Eagle was the Bourns trimmer resistor [Mouser #652-3386F-1-103TLF].  After a trip to google, I found an Eagle PCB Search site which had a link to a library containing the 3386 series components.  The library was hosted at Cadsoft USA, so a few clicks later I was downloading the parts library, and dumping it into my Eagle installation's LBR directory:

The final list of Eagle components needed for the schematic was:

• 2 x PINHD-1x2
• 1 x PINHD-1x4
• 1 x PINHD-1x16
• 1 x 3386-F (bourns.lbr)

After adding the parts, the wire tool was used to connect everything up.  A few wire junctions later, the schematic was complete (also verified by running the error checker with 0 errors found).

The next post will discuss converting this schematic to a board.
