Drawdio — Arduino — Maxmsp

[faeviuz]

Hi everyone,
I have just bought a Drawdio and I am playing with it.
Now I am trying to build an interactive fork, pretty much like this one:

I was thinking about connecting the Drawdio to an Arduino and then having Maxmsp to assign different samples/sounds depending on the reading received from Arduino.
While I can do this on both Arduino and Maxmsp, I don't know how I could get a reading from the Drawdio.
I have seen that there has been already another post re the same issue:
viewtopic.php?f=19&t=13376
Is this the only way of doing it? Can I do it connecting only two wires to the Arduino?

This is the code I'd use on the Arduino:

// these constants won't change:
const int sensorMin = 0; // sensor minimum, discovered through experiment
const int sensorMax = 600; // sensor maximum, discovered through experiment

void setup() {
// initialize serial communication:
Serial.begin(9600);
}

void loop() {
// read the sensor:
int sensorReading = analogRead(A0);
sensorReading = map(sensorReading, sensorMin, sensorMax, 0, 255);


Serial.println(sensorReading);
}


Many thanks for your help!

Best wishes
