I am trying to get an Arduino Nano to play a WAV file, but it's not working.
The wiring looks good, and the code seems to be ok;
ChatGPT suggests that one of the possible reasons for the problem could be incompatibility of the libraries i've installed. I have read the readme docs, but don't see any notes about that.
How could i check to see if the versions i've installed are compatible? or, if these libraries are dependant on some other library that i neglected to install??
your text
the code uploads fine
i flip the switch and exactly nothing happens
It should play a WAV file. It doesn't
This is the uploaded code:
#include <SD.h>
#include <TMRpcm.h>
#define SD_CS_PIN 10 // CS pin for the SD card reader
#define SWITCH_PIN 2 // Pin connected to the switch
#define LASER_PIN 3 // Pin connected to the laser
#define SD_MISO_PIN 12 // MISO pin
#define SD_MOSI_PIN 11 // MOSI pin
#define SD_SCK_PIN 13 // SCK pin
TMRpcm audio;
void setup() {
pinMode(SWITCH_PIN, INPUT_PULLUP); // Enable the internal pull-up resistor
audio.speakerPin = 5; // Set the speaker pin (any available PWM pin)
Serial.begin(9600);
if (!SD.begin(SD_CS_PIN)) {
Serial.println("SD card initialization failed!");
while (1);
}
audio.setVolume(5); // Set the volume (0 to 7)
}
void loop() {
if (digitalRead(SWITCH_PIN) == LOW) {
playSound("mp3/tos_phaser_7_01.wav"); // Play the WAV file when the switch is pressed
}
}
void playSound(const char* filename) {
if (audio.isPlaying()) {
audio.stopPlayback();
}
audio.play(filename);
}
