MP3 Player hot and the speaker doesn't emit sound

[naufalsaid_m]

Hello Guys
Sorry for asking so sudden, Im manage to build the device like periodic table, but using lcd and speaker to display the elements and emit sound description of the elements using arduino, sadly, when the first and second try,

It's working good, but on third try, it's not emit sound again, also the mp3 player it's getting so hot each time it's enabled, also it's only on using external electric source like powerbank or laptop, well my teacher already installed the battery inside, but it also looks like not powerful enough to power the device.

Im asking for your help, guys, cause Im actually a social program study in college and abso no idea how to repair this.

This is list of components I use for the project, and honestly I want to post the code here, but I don't know how to extract the code from the arduino board, Im already try to use guide from blackbox.ai, but it didn't work.

Arduino mega 2560
shield arduino mega
module MP3 TF 16p V3.0
Liquid Crystal Display 20x4
12C LCD 20X4
And also a speaker that I don't know the name

And here is the picture of the product

Do you have a schematic or wiring diagram for that mess of wires? Looking at it, I can see why you might have problems.

[naufalsaid_m]

Actually Im Also don't have it, or maybe I make it now, but Im also don't really understand the road of the cable.

[Paul_KD7HB]

When you make a diagram of the wiring, you may see the error.

[naufalsaid_m]

Can I ask how to make the wiring one ?, Im gonna try to make it, hope it can solve the problem, hopely....

@naufalsaid_m

how to make the wiring one ?

Pen or pencil on paper. And if the error still is not apparent, take a picture of it and attach it to a reply here.

Im doing what I know, some of the cable I can't connect together, like the correct way below
the MP3 player :
GND > G11
VCC > V11
RX > resistor > S11
TX > S10

SPK 1 & SPK 2 > Speaker

I’d like to help but unfortunately I cannot understand your English or see the details of your very poor photograph. Do you have a friend who can help? If so please:

1. Give us a link to the source of this project.
2. Show the sketch you are using,
3. Take photos that show clear details of every wire connection
4. Explain in detail exactly what you are trying to make
5. Confirm my asssumption that this is a school assignment

Use Google Translate if necessary.

Sorry for asking so sudden,

Yeah we never received any notice, but most of the shock is gone now.

I like your build, the wooden box with those branding marks etc. How do you pick an element, I can only see buttons for the columns?

The product seems to come from here...

[Terrypin]

Searching that interesting site I found nothing apparently relevant, did you?

Anyway, the OP (like so many) seems to have lost interest.

[xfpd]

I found nothing. I hoped for a syllabus. I tried YouTube, still could not find it. Perhaps a non-English youtube/google search is needed.

[Terrypin]

Good idea. But no joy after some to-and-fro with Google Translate.

Did find this loosely associated post:
https://forum.arduino.cc/t/coding-help-requested-for-interactive-periodic-table-with-ws2812b-leds-and-phone-app-as-controller-project-for-students/1308898

And a search with 'interactive periodic table arduino game' delivered several more.

(That was a fun project).

This "suka" project looks like selecting a "Chemical Group" with a button, and give audio with LCD output.

I'm going to guess they have the speakers and the TX/RX mixed because they are using all the same wire colors.
