Parsing and selecting data coming from Arduino

First, I want to introduce you to a helper firmware inspired by the Arduino2Max page on the Arduino website but updated and optimized a bit by me. It provides a way to read all the inputs on your Arduino, to pack all the data read, and to send them to our Max 6 patch through the [serial] object.

The readAll firmware

The following code is the firmware. You can find it in Chapter12/ReadAll:

int val = 0;

void setup()
{
  Serial.begin(9600);
  pinMode(13,INPUT);
}

void loop()
{ 
  // Check serial buffer for characters incoming
  if (Serial.available() > 0){         

    // If an 'r' is received then read all the pins
    if (Serial.read() == 'r') {       

      // Read and send analog pins 0-5 values
      for (int pin= 0; pin<=5; pin++){      
        val = analogRead(pin);
        sendValue (val);
      }

      // Read and send digital pins 2-13 values
      for (int pin= 2; pin<=13; pin++){     
        val = digitalRead(pin);
