WEB radio on ESP32-S3-WROOM-1 no sound or just a buzzer

Projects General Guidance
1

I’m trying to build a web radio basic schematic, from internet.

ESP32-S3 board and MAX98357.

I see the board connected to Internet on my firewall.

The URL connected to works perfect on my computer.

I tried different GPIO settings. Either I have sound like a buzzer or silence.

Serial monitor shows:

10.200.200.4


Total PSRAM: 8388608

Here is the sketch:


```cpp
#include <Arduino.h>
#include <WiFi.h>
#include <Audio.h>
#define I2S_DOUT     4
#define I2S_BCLK      5
#define I2S_LRC        14
Audio audio;
String ssid =    "P";
String password = "s";
void setup() {
  WiFi.disconnect();
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid.c_str(), password.c_str());
  while (WiFi.status() != WL_CONNECTED)
  delay(1500);
  Serial.begin(115200);
  Serial.println(WiFi.localIP());
  Serial.printf("Total PSRAM: %d\n", ESP.getPsramSize());
  audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT);
  audio.setVolume(100);
  //audio.connecttohost("https://playerservices.streamtheworld.com/api/livestream-redirect/CJFMFM.mp3");
  audio.connecttohost("http://vis.media-ice.musicradio.com/CapitalMP3");
  Serial.println("Music now");
}
void loop()
{
  audio.loop();
}
```

Please post mandatory schematics for a project like this. Know that we know only what You show us.

@Railroader Above is the basic diagram

Thanks. Looks rather okey.

From where does “5 volt” come?

@Railroader

Playing with the different GPIO settings I got working. I also added Internet connection OnDemand, based on Tzapu library. Next step to add a rotary switch to change the sations.

Help will always be appreciated.

Here is the current working sketch:


```cpp
#include <Arduino.h>
//#include <WiFi.h>
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager

#include <Audio.h>
#define I2S_DOUT     12
#define I2S_BCLK      13
#define I2S_LRC        14

// select which pin will trigger the configuration portal when set to LOW
#define TRIGGER_PIN 46

int timeout = 120; // seconds to run for

Audio audio;
//String ssid =    "P";
//String password = "s";
void setup() {
  //WiFi.disconnect();
  //WiFi.mode(WIFI_STA);
  //WiFi.begin(ssid.c_str(), password.c_str());
  //while (WiFi.status() != WL_CONNECTED)
  Serial.begin(115200);
  pinMode(TRIGGER_PIN, INPUT_PULLUP);
while (digitalRead(TRIGGER_PIN) == HIGH) { 
  Serial.println("\n Waiting for button");
  delay(1500);
  }
   WiFiManager wm;    

    //reset settings - for testing
    wm.resetSettings();
  
    // set configportal timeout
    wm.setConfigPortalTimeout(timeout);

    if (!wm.startConfigPortal("OnDemandAP")) {
      Serial.println("failed to connect and hit timeout");
      //delay(3000);
      //reset and try again, or maybe put it to deep sleep
      ESP.restart();
      //delay(5000);
    }


  
  delay(1500);
  Serial.begin(115200);
  Serial.println(WiFi.localIP());
  Serial.printf("Total PSRAM: %d\n", ESP.getPsramSize());
  audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT);
  audio.setVolume(100);
  audio.connecttohost("https://playerservices.streamtheworld.com/api/livestream-redirect/CJFMFM.mp3");
  //audio.connecttohost("http://vis.media-ice.musicradio.com/CapitalMP3");
  Serial.println("Music now");
}
void loop()
{
  audio.loop();
}

```

No. It comes from out ouf the sky.

So no remaining question, no more help needed?

Anyone can help implementing KY-040 360 Degrees Rotary Encoder, please?

10

@Railroader

I asked for more help, nobody answered.

11

Please post a link to the datasheet of the exact decider You've got.

12

@Railroader

Can you, please, elaborate?

13

Sorry. The bastard AI changed the message.

Please post a link to the datasheet of the exact encoder You've got.

14

@Railroader

KY-040 360 Degrees Rotary Encoder

15

Datasheet please.

16

@Railroader

17

Make a test code for the encoder and make it work. Start by using the example in the datasheet.

Then is the question how You want the encoder to affect the build.

18

@Railroader

Thanks, I will work on it, and I will let you know.

19

Please do. Know that there will be a need for a sum up for both code and wiring to give a clear overview.

@Railroader

I’ll do my best.

I’m trying to built a web radio. My first radio that I built, was a Galena!!! Now you know my age.
