I use a generic servo shield, and the servo PWM outputs (3 pin inline connector) on the shield are labeled accordingly (0 - 15). Your Adafruit servo shield should be the same, see below.
The link that you provide also has the Arduino version, see below. You should use that, instead of the Processing version.
The Arduino library Servo.h, handles all of the "Servo PWM to Arduino pin conversions" that you ask for. So, looking at the Fixbot code, it would seem that all you would need to do is change the five pins (servo PWM outputs) to which the servos are attached in setup(), according to which servo PWM outputs you attach each servo to.
#include <Servo.h>
String command;
Servo seg0;
Servo seg1;
Servo seg2;
Servo seg3;
Servo seg4;
void setup() {
Serial.begin(115200);
seg0.attach(8); /* <--- Change Me !!! */
seg1.attach(9); /* <--- Change Me !!! */
seg2.attach(10); /* <--- Change Me !!! */
seg3.attach(11); /* <--- Change Me !!! */
seg4.attach(12); /* <--- Change Me !!! */
}
void loop() {
if(Serial.available() > 0) {
char inChar = Serial.read();
command += inChar;
if(inChar == '\n') {
// clear command
performCmd(command);
command = "";
}
Serial.flush();
}
}
void performCmd(String cmd) {
int comma1 = cmd.indexOf(',');
int comma2 = cmd.indexOf(',', comma1+1);
int comma3 = cmd.indexOf(',', comma2+1);
int comma4 = cmd.indexOf(',', comma3+1);
int cmd0 = stringToInt(cmd.substring(0, comma1));
int cmd1 = stringToInt(cmd.substring(comma1+1, comma2));
int cmd2 = stringToInt(cmd.substring(comma2+1, comma3));
int cmd3 = stringToInt(cmd.substring(comma3+1, comma4));
int cmd4 = stringToInt(cmd.substring(comma4+1, cmd.length()));
seg0.write(cmd0);
seg1.write(cmd1);
seg2.write(cmd2);
seg3.write(cmd3);
seg4.write(cmd4);
}
int stringToInt(String str) {
String tmp = String(str);
return str.toInt();
}
Regarding your question about the maximum and minimums, again, these will be handled by the Servo.h library.
TL;DR
Change the five servo attach lines in the setup() routine, to reflect which servo ports your servos are connected to.
Power Requirements
As an aside, remember that you will need to supply external power (+5V) to the Adafruit Servo board, via the blue screw terminal block, in order to have sufficient power (current) to actuate the servos. In the photo above the screw terminal block is not shown, but would be mounted half way up on the left hand side of the PCB (where it says 5-6V Servo). It can be seen in this photo, at the top:
If you do not supply external power, then the Arduino board, by itself will not be able to supply enough power. Even though the code may be running, the lack of power may make it appear that there is no output, as the servos remain immobile, due to the lack of current.
