Updated jawduino code to control a servo based on sound

talkingskull.ino

#include <Servo.h> // Standard servo library

Servo myservo;
#define SERVO_PIN 9     //  Set to the controller pin for the servo

int servo_pos = 0;
int val1;               //  Floating value 1
int val2;               //  Floating value 2
int val3;               //  Floating value 3

char smon[30];           //  Serial monitor buffer

void setup() {
  myservo.attach(SERVO_PIN);
  Serial.begin(9600);
}

void loop() {
  //  Set our initial servo position:
  servo_pos = 0;
  
  //  Read our (floating) LED values
  val1 = analogRead(A1);
  val2 = analogRead(A2);
  val3 = analogRead(A3);

  if(val1 < 341) servo_pos += 60;
  if(val2 < 341) servo_pos += 60;
  if(val3 < 341) servo_pos += 60;

  //  Debugging:  Use the arduino IDE serial monitor to see these values
  sprintf(smon, "A1:%4d A2:%4d A3:%4d Pos:%4d", val1, val2, val3, servo_pos);
  Serial.println(smon);

  //  Set the servo position:
  // val1 = map(val1, 0, 1023, 0, 180);  
  myservo.write(servo_pos); 
  
  //  Tiny delay:
  delay(15);
}

Use the same audio processing chip mentioned here: http://buttonbanger.com/downloads/jawduino/jawduino.pdf along with the same solder points (see 'where to solder' and picture)

One thing I still don't understand is the magic numbers used in these lines

having trouble with map function

pop

What's the problem you're having with the map function? (It's currently commented out)
