As [Kalanda] published on its blog (spanish) and github, there is one more (easier) way to establish connection with an Arduino over a network connection (among the others):
serial2socket-proxy is a cross-platform software application developed in Processing for creating a virtual connection between the serial port and a network socket port.
For example, you can control an Arduino board connected to the serial port from any computer over internet. Also you can use this socket connection for communicate with your arduino board from Flash/Air application programmed in Actionscript, a PHP application or whatever language that can access to a socket

As part of the National Robotics Week coverage of iheartrobotics, the Vibratron:
[...]the newest member of the RobOrchestra. This amazing musician was built by club members with a total budget of $1000. The Vibratron uses an Arduino Mega to control 30 individual solenoid gates which drop steel balls onto the vibration keys. Using the Arduino Mega they were able to avoid complications with multiplexing I/O lines. Notes are read in using a MIDI shield to receive standard MIDI signals from a sequencer or keyboard. The balls are recirculated using an Archimedes screw to raise them to the bucket at the top.
[Andrew Burks] the project leader from the CMU Robotics Club, offered to have the Vibratron perform musical compositions submitted from the internet.
Anyone who has a song they want us to play, a question about the group, or a suggestion for our next instrument, should contact roborchestra =at= roboticsclub.org
If you want to compose music for the Vibratron, there are only a few things you need to know:
It is set up to play MIDI notes 48-77.
- It listens on channels 3 and 13. The difference being, on channel 3 any notes out if its range are ignored, while on channel 13 any notes out of its range are transposed to the closest octave.
- It only plays NoteOn commands, and the velocity needs to be set greater than zero.
- It cannot play more than around 10 notes at once (because of power limits). the xylophone has no such limitations.
- The Xylobot is the same, but on channels 2 and 12 for MIDI notes 60-76
Any MIDI files we get before May we will record the robot playing and post by mid-May.
