in vvvv you can use the RS232 and regex object to receive data and translate the ASCII values back to decimal.
check the vvvv regex documentation for details. in the following patch i used a(\d+)z for the parsing, that's an 'a' followed by one or more numeric values, followed by a 'z'. patterns in brackets () will be shown as outputs in the regex object.
Arduino code (you may have to adjust the baudrate):
void setup() {
Serial.begin(19200);
}
void loop() {
Serial.print('a');
Serial.print(analogRead(0),DEC);
Serial.print('z');
}
ASCII - decimal conversion
serial data between arduino and the computer is sent in ASCII format. values have to be translated back to decimal. http://www.asciitable.com/

Arduino Clones
Mit etwas Erfahrung kann man sein eigenes Arduino designen oder ein bestehender Clone nachbauen. Nebst dem Löten der Bauteile muss der Arduino Bootloader auf den ATMega geladen werden. Ist der Bootloader einmal auf dem chip, kann das Arduino mit einem USB zu Serial Interface (z.B. FTDI Basic Breakout - 5V von sparkfun) programmiert werden.
