All Analog Inputs to MaxMSP by BARRAGAN http://barraganstudio.com
Demonstrates how to print data to the serial port. The data is received by MaxMSP. The MaxMSP patch is included below as text. Copy the text of the patch open a new patch in MaxMSP and paste.

    void setup()
    {
      Serial.begin(9600);
    }

    void loop()
    {
      Serial.print(analogRead(0), DEC);
      Serial.print(",");
      Serial.print(analogRead(1), DEC);
      Serial.print(",");
      Serial.print(analogRead(2), DEC);
      Serial.print(",");
      Serial.print(analogRead(3), DEC);
      Serial.print(",");
      Serial.print(analogRead(4), DEC);
      Serial.print(",");
      Serial.print(analogRead(5), DEC);
      Serial.print(",");
      Serial.print(analogRead(6), DEC);
      Serial.print(",");
      Serial.println(analogRead(7), DEC);
      delay(100);
