Buzzer does not make sound

Hi,
I have grove base kit for Raspberry Pi and the buzzer does not make any sound.
Buzzer is connected to PWM port. I am running basic Grove_Base_Kit_Sketchbook/Tutorial_01-Buzzer script. What should i do? How can i investigate a problem? Its brand new. It is possible that buzzer is broken?

i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f

Hi @chkuba
The Grove Base kit is not a Dexter Industries product, and we have no experience with it. We deal with the GrovePi+ exclusively.

You will have to contact Seeed for help on this one.

Greetings and welcome in from both myself and my 'bot Charlie, AKA “The Bug-Mobile”.

Cleoqc is right, this is a SEED studio issue, but looking at your post, a few things jump out at me:

  1. You mentioned that the buzzer works with PWM.
  2. On the other hand, you show an i2c map from i2cdetect.

On the Pi, (at least!), PWM and i2c are two separate and distinct interfaces, using different pins and different programming.

Maybe you are inadvertently “barking up the wrong tree”, and selected the wrong code to test it with?

If so, welcome to the club! That’s a mistake I’ve made before too.

Anyway, welcome! After fussing with that thing, if you decide to get a GoPiGo, come on back over and show us what you’re doing.
