1  Forum 2005-2010 (read only) / Workshops / Arduino Intro at Dorkbot DC Feb. 20 on: February 16, 2007, 12:02:34 pm
I will be giving a "Hello World" style introduction to the Arduino at the next Dorkbot DC meeting:

Tuesday, February 20, 2007
7 PM - 9 PM (ET)
Provisions Library
Suite 200
1611 Connecticut Ave. NW
Washington, DC 20009 USA
(above Ann Taylor Loft)

We're expecting to have a number of Arduino enthusiasts in the audience as well.

New Update:

Yep, I had old firmware.  I downloaded the newest firmware from Vinculum (, and renamed it "ftrfb.ftd" and put it on a thumb drive.  I powered it up, and it reflashed the firmware.

Now I'm at "Ver 03.56VMSC1".

Good news: There is some evidence that it sends out the "Playing 1.MP3" style messages once you start playing.

Bad news:  Now bringing CTS high appears to stop playback, although that is the only way you can receive serial data from the device.

Ack!  Looks like I'll have to bang on it some more.

To date, I've been able to get back an answer to a "DIR" command, but I can't seem to get the VMUSIC2 to properly indicate when an audio file is done playing (I don't even get the command prompt back).

I thought that perhaps I'd have to upgrade the firmware, but it gives "Bad Command" when I try to "FWU" it.

On the other hand, I seem to have no problem playing back files using "V3A" or "VPF".

UPDATE:  It turns out that my firmware is so old (Ver 01.12) that it doesn't even have the FWU command...I'll have to ask Vinculum to see what I can do about upgrading the firmware.

Yep, well if you take the CTS# pin HIGH you certainly can data coming in from the VMSUIC2.

Unfortunately, the only thing I've been able to read so far is:

"Ver 01.12VMUSIC1 On-Line:
No Upgrade

While I'm getting the "login message" and the "command prompt", the information about playback doesn't seem to be coming in for some reason - obviously the neat part would be for the VMUSIC2 to tell you when a clip has done playing.  There might be some weird configuration issue I am missing.

Of course, if you know how long the clip is ahead of time, you can just delay() until it is over.

My thought is that for two-way, you will need to toggle the VMUSIC2 CTS#, so instead of just grounding that pin, you'd attach it to a digital output pin and do something like

digitalWrite(CTS_pin, LOW);
Serial.print("V3A"); #play all files
digitalWrite(CTS_pin,HIGH); #allow data to be transmitted from the VMUSIC2 to the Arduino
while (Serial.available() > 0) {
            incomingByte =;
... # do something with it

Unfortunately I can't test this for a few days...too many projects going on at the same time!  But I'll post results if it works.

I worked out how to use the Vinculum VMUSIC2 MP3 player with the Arduino.  The VMUSIC2 uses USB flash drives to store MP3 audio.

That's awesome!   smiley

It certainly would be great to get Ethernet on the Arduino board, but it is probably a little much for the ATMega to do all the TCP/IP/DHCP stuff.

I suggest looking at combining a serial-to-Ethernet ASIC based system like:


or what I've used, the Xport which is very solid and easy to use:

or the cheaper Xport Direct:

Great info folks!  Here are URLs with info about the arm-wrestling over IP at the museums:,1759,1730854,00.asp

I'd like to introduce Phy2Phy, a project to nurture the creation of networked artworks that link one physical world with another physical world over the Internet.

This can include interactions such as:

Touch-to-Touch       Motion-to-Motion                               Heat-to-Heat
Breath-to-Breath     Musical Instrument-to-Instrument       Pain-to-Pain
