Laser Harp issue please help

e14 Contributor

Good Evening,

 

I was hoping you could help I am attempting to build a laser buzzer type harp with my Arduino I have followed a tutorial I found online however when it came to the programming I am experiencing an issue Error compiling

 

 

C:\Users\Scott\Documents\Arduino\libraries\Tone\Tone.cpp: In member function 'void Tone::begin(uint8_t)':

C:\Users\Scott\Documents\Arduino\libraries\Tone\Tone.cpp:121: error: 'bitWrite' was not declared in this scope

C:\Users\Scott\Documents\Arduino\libraries\Tone\Tone.cpp:123: error: 'digitalPinToPort' was not declared in this scope

C:\Users\Scott\Documents\Arduino\libraries\Tone\Tone.cpp:123: error: 'portOutputRegister' was not declared in this scope

C:\Users\Scott\Documents\Arduino\libraries\Tone\Tone.cpp: In member function 'void Tone::stop()':

C:\Users\Scott\Documents\Arduino\libraries\Tone\Tone.cpp:361: error: 'digitalWrite' was not declared in this scope

 

here is the tutorial I have followed: http://www.radioshack.com/graphics/uc/rsk/Support/ProductManuals/Laser_Harp_Online_Instructions.pdf

 

Here is the code:

 

#include <Tone.h>

 

const boolean DEBUG = false;

 

const int CALIBRATION_PIN = A5;

const int SPEAKER_PIN = 8;

const int SENSOR_COUNT = 3;

 

typedef struct

{

  int pin;

  int note;

} sensor_type;

 

sensor_type sensor[SENSOR_COUNT];

 

Tone notePlayer;

 

void setup(void)

{

  if (DEBUG) {

    Serial.begin(9600);

  }

  sensor[0].pin = A0; // analog input 0, etc...

  sensor[0].note = NOTE_G3;

  sensor[1].pin = A1;

  sensor[1].note = NOTE_D4;

  sensor[2].pin = A2;

  sensor[2].note = NOTE_A4;

 

  notePlayer.begin(SPEAKER_PIN);

}

 

void loop(void)

{

  int calibration = analogRead(CALIBRATION_PIN);

  if (DEBUG) {

    Serial.print("cal: ");

    Serial.print(calibration);

  }

  int activeSensor = -1;

  for (int p = 0 ; p < SENSOR_COUNT ; p++) {

    int sensor_value = analogRead(sensor[p].pin);

    if (DEBUG) {

      Serial.print("\tsensor ");

      Serial.print(p);

      Serial.print(": ");

      Serial.print(sensor_value);

    }

    if ( sensor_value < calibration ) {

      activeSensor = p;

      if (DEBUG) Serial.print("!"); // "!" indicates note being played

    }

  }

  if (DEBUG) Serial.println();

  if (activeSensor == -1) {

    notePlayer.stop();

  } else {

    notePlayer.play(sensor[activeSensor].note);

  }

  if (DEBUG) delay(1000);

}

 

I look forward to your reply thanks in advance!

  • Trusting that a few of you out there may be experimenting with this sketch using Arduino 1.0, further research seemed to be in order.

     

    Doing so, just for fun, earned an inglorious reward: a bucket full of error messages from the IDE and a very unsuccessful compile.  The first "red line" warning told the whole story:  "C:\Users\microwattbott\Documents\Arduino\libraries\Tone\Tone.cpp:26:20: warning: wiring.h: No such file or directory"

     

    Due diligence brought me to: http://blog.makezine.com/2011/12/01/arduino-1-0-is-out-heres-what-you-need-to-know/

    Where something unexpected was learned about migrating libraries into the new and improved Arduino 1.0 IDE. 

    If your sketch includes any libraries that have not been designed for 1.0 
    then you will need to change the library if it uses any of the old header files 
    that have been replaced with the new Arduino.h file. If you include any 
    of these libraries, change:
         #include "wiring.h" 
         #include "WProgram.h" 
         #include "WConstants.h" 
         #include "pins_arduino.h"
    To
         #include "Arduino.h"

     

    The fix was made by opening the library, Tone.cpp, for editing and the reference to wiring.h was replaced with the suggested Arduino.h.  Saving and recompiling the sketch was done with ease and success (queue marching bands and cheering crowds).

    thanks for your help I resolved the issue, then received another issue something to do with the drivers but its all fixed now. I have one more issue when I shine a laser over the sensors it beeps instead of it making the noises once the laser beam was broken can anyone be kind enough to help me with the code?

    Redo the the Calibration steps.

    Troubleshooting

    If it’s not working...

    • Check all connections. Make sure all components and jumper wires are

    in the appropriate rows in the solderless breadboard. Make sure you’ve

    connected to the correct pins on the Arduino. 

    • Use a multimeter to test your circuit. Hook it up in voltage testing mode

    to test the voltage coming from each photoresistor (In the illustration and

    photo above, you would test the blue, green and yellow wires coming from

    each sensor. Unplug each wire in turn from the Arduino and test the voltage

    across the wire and ground. The voltage should vary as you block and

    unblock the sensor).

    • Use a multimeter to test the resistance of the photoresistors. A fully blocked

    photoresistor should be in the same ballpark as the fixed (non-photo) resistor

    in the voltage divider circuit. If the resistance is significantly different (e.g., 10K

    vs. 100K), try to find a photoresistor in the correct range. Otherwise,

    replace the fixed resistor with one of a similar value as the blocked photoresistor.

     

    If you want to see what’s going on in the Arduino program, turn on debug input in

    the sketch by changing this line:

    const boolean DEBUG = false;

     

    To this:

    const boolean DEBUG = true;

     

    Turn on the Serial Monitor in Arduino while the program is running, keeping the

    USB cable connected.  This will print some interesting information to the screen

    as you play your harp, but it will negatively affect its performance; there will be

    a lag as you block and unblock the beams.
