Playing .wav files

Projects Programming

I am trying to make a csgo bomb prop for me and my friends to use while we play airsoft. I am trying to add audio in for when the bomb is armed(planted.wav), disarmed(ctwin.wav), and when the timer runs out(twin.wav). Here is my code:

#include "pitches.h"
#include <LiquidCrystal.h> //include LCD library (standard library)
#include <Keypad.h> //include keypad library - first you must install library (library link in the video description)
#include "SD.h" //Lib to read SD card
#include <pcmConfig.h>
#include <pcmRF.h>
#include <TMRpcm.h>
#include "SPI.h" //SPI lib for SD card


#define SD_ChipSelectPin 11 //Chip select is pin number 11
TMRpcm tmrpcm; //create an object for use in this sketch

char password[8] = "7355608"; //create a password
int pozisyon = 0; //keypad position
int time=19; // countdown time
const byte rows = 4; //number of the keypad's rows and columns
const byte cols = 4;
int speakerpin=8; 
int freq=2000;
int dur=120;
int codepos=0;
int interval=1000;
int previousMillis = 0;

char keyMap [rows] [cols] = { //define the cymbols on the buttons of the keypad

  {'1', '2', '3'},
  {'4', '5', '6'},
  {'7', '8', '9'},
  {'*', '0', '#'}
};

byte rowPins [rows] = {7, 6, 5, 4}; //pins of the keypad
byte colPins [cols] = {3, 2, 1};

Keypad myKeypad = Keypad( makeKeymap(keyMap), rowPins, colPins, rows, cols);

LiquidCrystal lcd (A0, A1, A2, A3, A4, A5); // pins of the LCD. (RS, E, D4, D5, D6, D7)

void setup(){

  lcd.begin(16, 2);

      lcd.print("    CT'S WIN");
      ctwin();

void twin(){

char keyget(){

And I get this error:

You didn't mention any problem, so, should we assume that you don't have a problem?

One thing I notice is that your time variables are 'int' but millis() deals in 'unsigned long' so your timing won't work very long when you overflow the size limits of an int.

Sorry the error messages are

C:\Users\tobyw\Desktop\Arduino\csgo\csgo.ino:67:28: warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]

C:\Users\tobyw\Desktop\Arduino\csgo\csgo.ino:162:25: warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings]

So, where are the error messages?

Twilks:
I get these error messages when I try to upload the code

warning != error.

Feel free to ignore the warnings.

The function you are calling incorrectly expects a char *. A string literal, like you are supplying, is a const char *. Until the library owner gets a clue, and fixes the code to expect a const char *, the warnings will persist.

You could, of course, cast your const char * to a char *, if the warnings bother you that much.

   tmrpcm.play((char *)"twin.wav");

Twilks:
When I upload the code, the arduino does not play the sound files though

That sounds like a hardware problem.
