Good day everyone,

 

I was wondering if the piezo buzzer can be used in any other Pin other than the Pins.GPIO_PIN_D9?

 

Thanks

Hi,

 

D10, D5, D6 are also PWM on the V1's.

 

Plus D3 & D11 on the v2's.

 

You could also make short bursts of sound using the SPI - MOSI (D11).

 

Have fun - Paul

Thanks Paul for your feedback, my bad, I was using D2 instead of D3 in my N+2 because I have read the following specs incorrectly:

 

digital pins 2-3: UART 2 RX, TX/PWM

 

And that was causing the board to crash really bad to be point that I had to re-flash it every time I was debugging my app.

for testing and such i suggest using a thread.sleep(5*1000); at the beginning _before_ your code, so when you reset it it gives you enough time

to just remove the app or deploy a new one before it crashes again.

 

(and seriously, 5 seconds is not really that long ...)
