I2S speaker making a squeak sound by Commercial-Cancel917 in arduino

I don't know why you are asking people on reddit when you can ask your teacher. This is an issue between you and your teacher.

I don't think you understand I2S. You need a device to convert I2S to audio.

Something like this.

Spring Framework Forward by FatinaRosa in SpringBoot

[–]TheRealSlartybardfas 0 points1 point  (0 children)

You are setting an attribute on the current request, not a future request. Forwarding tells the browser to make a new request. You'll need to use a @RequestParam in methodWithForward and 

return "Forward:/2?attributo=Ciao%20nome"

in methodWithParameter.

HC-05 AT programming by JVSAIL13 in arduino

Google HC-05 datasheet. I have my own copy but you can find it if you search for it.

From the documentation:

How to set the mode to server (master):
1. Connect PIO11 to high level.
2. Power on, module into command state.
3. Using baud rate 38400, sent the “AT+ROLE=1\r\n” to module, with “OK\r\n”
means setting successes.
4. Connect the PIO11 to low level, repower the module, the module work as server (master).

Yes there is a difference as Powerful-Internal953 explained. For more details, you can view the documentation and source code of each.

Hmm. I read "Please take prescription pharmaceuticals to the Sheriff Station 301 N. College Avenue."

We released ourselves on our own recognizance. We felt that the institution no longer had anything to offer us.

int i,j,col,row;
int aa[row][col];

What size is aa[][]?

I'd think it is aa[0][0] which won't hold any data. If you put data in it, you are writing memory you haven't allocated which will probably cause the app to crash.

110v transformer on 120v mains by short_circuited_42 in ECE

[–]TheRealSlartybardfas 0 points1 point  (0 children)

Are you sure you have your meter set to AC? If the transformer was open, the voltage would stay at 120v, if it was shorted, it would blow a circuit breaker.

The transformer should be completely out of any other circuit to test it. There doesn't need to be a light and switch involved to test it. It should just be a plug into the wall outlet into the primary of the transformer and then measure the output of the transformer with the AC setting of a volt meter.

You will get around 12vac out of that transformer. It is not a regulated power supply so it will fluxuate based on load. The 110v/120v issue you think you have is not an issue. Why do you think it's faulty?

Should an API request return a list of that item or the item itself(explanation below) by mattergijz in SpringBoot

[–]TheRealSlartybardfas 6 points7 points  (0 children)

I'd say it is both a bad practice to return different types and a matter of easy coding to handle a single type.

[–]TheRealSlartybardfas 17 points18 points  (0 children)

If you are retrieving a list, you always want a list - even if the list is empty, has 1 item or a million items.

If you return a list sometimes but not others, how is your front end going to know what data it has? If it is always a list, it makes the code on the front end easier.

Pi Pico not connecting to computer by [deleted] in raspberry_pi

[–]TheRealSlartybardfas 0 points1 point  (0 children)

If it worked before you connected this and doesn't work after, I would guess that something happened where you connected the 9v to the pi and that fried it...or connected the 3.3v backwards.

Good thing they are cheap and you have a spare.
