Multifunctional Shield Buzzer does NOT work

Other Hardware General Electronics

Hi All,

I just got a new Multifunctional Shield that has a Buzzer on it.
I tried to install the directories and I managed to find several that I can use BUT on each, I could NOT have the BUzzer to work.

How can I test the Buzzer? anyone had the same issue as I do?
what is the CORRECT Library to install for the multifunctional Shield?

this is the one I have - with RED Buttons.
Not sure that there is a big difference from the black buttons one - But I you'll never know.

I have tried several times to make the Buzzer work and I could NOT do that.
Also, I have tried to run examples and I am getting wired digits and numbers on the 7Segs instead of what I should have.

I am NOT sure that I am using the correct directory or maybe my board is No good.
I would be happy if someone can assist me with that so I will be able to work with it and test the functionality of the board as well.

Please let me know where I should get the directory files for that board and examples.
I would like to make the buzzer work and test the board.

Thank You!
Arye

If you haven't already, checkout this pdf on the mfs.

It has a lot of usefull info and should get you up and running. Also youtube is a great resource for info.

I'm sure this isn't the problem, but pull-off the protector that says "remove..." It's covering-up the hole where the sound comes out.

Thanks.

I have already downloaded the PDF from Hackatronics and followed instructions from there. Also the Piezzo is not covered at all I have removed it when I got the Shield.

Any idea how I can troubleshoot this and see what is wrong?
Please assist me the correct Library to use with the Multifunctional Shield.

Maybe the one linked from the PDF is NOT the one I should use with mine.

Please assist,
Thank You!

The buzzer seems connected to pin3.
Try this test sketch.
Leo..

const byte buzzerPin = 3;

void setup() {
  pinMode(buzzerPin, OUTPUT);
}

void loop() {
  digitalWrite(buzzerPin, HIGH);
  delay(1000);
  digitalWrite(buzzerPin, LOW);
  delay(1000);
}

Thanks But it does NOT seem to work. Nothing to hear.
Maybe the Buzzer is NOT working.

I use hundreds of these buzzers per year, and the failure rate of some batches is >10%.
Could well be a dud.
Easy to replace if you can solder.

Nope! the Buzzer is working - it looks like there was no connection to the + leg of the Buzzer. When I connected a wire from pin 3 to the leg - it works. it is a faulty shield.
