Buzzer won't on my code; i testes it by itself and its working but when i put it on my main code i does not work;

ahmed6666 · May 31, 2022, 11:42am

i tried to figure out from where the problem is and i concluded its from the fingerprint sensor it makes no sense but it's happennenig and now am really confused
PS : void buzzer() and the pinMode in void configurationBroche() are the ones wich concerne the buzzer the rest of the code is working properly
PS 2: the buzzer is just an alarme when the door still open after a specified delay thats all

Put some serial prints in (start with buzzer) to see what's going on.

me either thats why it confuses me
is there any possibility that the problem is from the ESP8266 ?

ahmed6666 · May 31, 2022, 1:01pm

its the same

kolaha · May 31, 2022, 1:03pm

and you say if anything else is disconnected the buzzer start to work, yes?

Idahowalker · May 31, 2022, 1:09pm

Which ESP8266 are you using?

Post an image of your wiring with the buzzer connected.

Post a schematic.

Post, below, the latest version of the code you are using.

ahmed6666 · May 31, 2022, 1:16pm

no, as i said the code but the buzzer work properly thats why i didnt connect the fingerprint sensor i just connected le LCD and it works, what i meant is that i built the buzzer code out of my main code and it worked (thats how i built my code step by step and then it ends in a single file) so i tried to put the buzzer in every single file and it worked except in the test of fingerprint file

Well thanks for posting the project image. I am confused that the devices used in the code like the fingerprint sensor or lcd is not connected. You do know the setup() does not properly WORK if those devices are NOT connected?

Sorry I cannot help you. Good luck with your project.

ahmed6666:

void buzzer(){
  EtatdePorte=digitalRead(12);
  
  if (EtatdePorte == HIGH){
    tone(14, 400);
Serial.println("buzzer should be working";
digitalwrite(13,HIGH);
  }
  else{
    noTone(14);
Serial.println("buzzer off");
digitalwrite(13,LOW);
  }
  delay(200);
}

I would start there and see what happens, its possible that one of the librarys used here is conflicting with the Tone function.
if you see the serial output or the LED illuminate then you at least know that the code is meeting the requirements for the tone to be generated. then you can troubleshoot why it doesnt generate.

ahmed6666 · June 1, 2022, 8:52pm

the pin 13 in digitalWrite is for what ?

spruce_m00se · June 1, 2022, 8:57pm

that will turn the built in LED on that is on pin 13

TomGeorge · June 1, 2022, 10:49pm

Hi,
Where in your code is the pinMode statement for the buzzer output pin?
