Hello everyone,
I just bought the subject item at Fry's Electronics:
http://www.frys.com/product/6726995;jsessionid=jChdtuzzoKANrd8+LpeFyQ__.node2?site=sr:SEARCH:MAIN_RSLT_PG.

Mfr: PARALLAX
Parallax Model: 27977-RT
FRYS.com #6726995
UPC: 644890279773

And using the info I found at parallax.com
Ardunio example:http://learn.parallax.com/kickstart/27977

I was able to make a Happy Birthday song by doing the following.

Found the musical notes for the song on the internet. http://www.8notes.com/scores/1110.asp
Converted the notes to decimal command codes (both lenghth and tone) (see image below).
Typed it into the Arduino IDE (see code below).
Uploaded to the Arduino UNO.

Steps 1 and 4 are fairly easy, but steps 2 and 3 were very time consuming.
MY FIRST QUESTION: Does anyone know or have suggestions of an easier way of doing steps 2 and 3?I was unable to figure out how to set the length of a note to 3/16 or 3/4.
Here's the list I found, as noted in the link above for Decimal Command Codes:

Dec Hex Action
208 D0 Set note length to 1/64 note
209 D1 Set note length to 1/32 note
210 D2 Set note length to 1/16 note
211 D3 Set note length to 1/8 note
212 D4 Set note length to 1/4 note
213 D5 Set note length to 1/2 note
214 D6 Set note length to whole note (2 seconds)

MY SECOND QUESTION: Does anyone know how to set the length of a note to 3/16 and 3/4?

Arduito - great question, good information given.

Do be aware that while there may be forumistas here that understand the Arduno language, we're primarily Parallax-oriented.

You can d/l the docs for the LCD here: http://www.parallax.com/Portals/0/Downloads/docs/prod/audiovis/27976-7-9-ParallaxSerialLCD-v3.0.pdf

That may have the information you're looking for.
The little module =is= fun to play with!
