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 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);
