Here's the max patch for part 3 of the tutorial.
I haven't had a chance to write up the tutorial itself, so for now, just download it, try it out - then examine the patch and see if you can figure out how it all works.

Here's the introductory patch that we built in the September 4th class.

Jitter is incompatible with Java 1.6
A fix or this from the processing forums:
1) On Windows, find the file C:\Program Files\Cycling '74\MaxMSP 4.6\Cycling '74\java\max.java.config.txt
2) Open it with a text editor (Wordpad works best)
3) Find the line that says: max.jvm.option -Xms16m
4) Change it to read: max.jvm.option -Xms64m
5) Save the file
Here is a concise all-in-one Max primer, designed around a Quicktime player patch that we built during the Max/MSP workshop last semester:

And here is the actual Max patch.

If you search the Arduino site for 'servo', you can turn up a couple of other methods as well, but I think Tom Igoe's method (above) is the best.
This version has some extra added bells and whistles for Jorge's project.

Download patch & script
Just in case you have any trouble opening the Arduino script, here it is for you to cut and paste:
//Arduino to Max example - to be used with accompanying Max patch
int incomingByte = 0; // for incoming serial data
void setup() {
Serial.begin(9600); // opens serial port, set baud rate
}
void loop() {
if (Serial.available() > 0) { // send data only when a byte is received
incomingByte = Serial.read(); // read the incoming byte
Serial.print("I received: "); // say what you got
Serial.println(incomingByte, DEC);
}
}
I think the newest version of the serial object for Windows may solve various problems for the WinTel tribe:

Here's are some circuit diagrams for driving relays from a microcontroller. Make sure you're using a 5-volt relay (this refers to the coil, not the load circuit), and make sure that the relay has a high enough rating for the load that you're driving.
This circuit is necessary if you are using a relay with a coil that needs more power than the microcontroller can supply (this includes most miniature electromechanical relays):
Troubleshooting:
• Make sure that you have the pins correctly labeled on the relay; different relays have different configurations.
• The diode protects the circuit in case the polarity is reversed. The stripe on the diode should be towards the 5v side.
• The base pin on the transistor is usually the center pin; consult documentation to distinguish the collector from the transmitter.
• If the relay is working correctly, you should be able to hear a little 'click' when you trigger it (except when using a solid-state relay).
Some relays (such as reed relays and solid-state relays) have coils that can be switched directly from the microcontroller, in which case you can use a less complex circuit:
Finally: if you're switching an AC device, PLEASE BE CAREFUL. Make sure you've got the coil working BEFORE you hook up the AC load. Make sure you have correctly labeled all the pins on the relay - NEVER connect AC voltage directly to the relay coil. Build your AC circuit BEFORE you plug it in. If you're not sure, ask someone to check it for you first.
This patch (when saved in a folder containing a bunch of Quicktime files) will automatically play each movie, one after another. It uses the 'loopreport' attribute, which causes jit.qt.movie to send the message 'loopnotify' out of its right outlet whenever it gets to the end of a movie (actually when it gets to the end of a loop, but by default the loop is set to the entire movie).

A wonderful MSP patch by Paul Hertz that produces all kinds of cheesy science fiction sound effects. It's also a great tool for learning how MSP works.

Here is another way of doing the photobooth trick WITHOUT using OpenGL -- it's much simpler and works beautifully. Includes some documentation.
