【MP3】DFPlayer Mini with ATtiny13A【DIY】

By connecting a microcontroller to DFPlayer Mini, even if the power is turned off, the volume setting and the song data you were listening to will be recorded in the EEPROM of the microcontroller.
When you turn on the power, the beginning of the song you were listening to will be played.

Hello, nice work done here ! I tried it on an ATtiny13A-PU using AVRISP XPII (ISP prog) through atmel studio v7 (also using the DFPlayer-mini). I also did a small PCB in order to have a clean result (powered by a 5v usb converter) hehe. In order to give some help/info to people here willing to try this project, here is some things that are good to know about this stuff : - If you're going through a basic installation of Microchip Studio v7 and using the listed materials here (hardware & code), you will probably meet a ".text section" error about the .ELF when you compile the code. This can be solved by changing some compiler parameters (don't mess your µC). You can also just replace (line 62) "if(res[3]==0x48){total=res[6];} //Total Number" to a smaller (line 62) "total=X; //Total Number" with "X" the integer number that correspond to the amount of sound stored on the SD-Card (eg : total=6;). Since we're talking about some bits overflowing the region, this will fix it ! - About the DFPlayer itself, you will find different file naming strategies which can be defined (eg: "0001.mp3" or also a folder hierarchy solution). Be careful about it, since some versions (red/blue leds) of the DFPlayer are considering the file position (#1, #2, #3, ...) about the "moment/order you inserted it in the SD card" and not about the "file name". Anyway, nice use of this small µC ! Hope it will help some people ! :)

I made the music box from his other dfplayer tutorial but it doesnt skip song when i open box,it just repeats first song on microsd.Do you know correct filename for red dfplayer.When i tested before soldering to attiny13a the filename didnt matter but does the atttiny13 require differrent filename to skip song?i tried 001.mp3 and 0001.mp3 but still only plays first song only.Do you know how to fix? kzbin.info/www/bejne/jqScap2No56Afqc

Neat little project! I’d also quite like to add a display or indicator lights or whatever, though before all that I’d move the project from perfboard to a slick home-etched board. Fold the legs of the DIP8 into an SMD, ditch the pin headers, etc. in order to make it less prickly in the pocket. Though I’ve not seen your channel yet, it would be nice to see an ATtiny13 + RDA5807 (or TEA5767) FM radio project.

diorama111 さん , do you have the reference link or part number for the prototyping board at 01:25 ? It is a very clean and easy color prototyping board, I hardly see such smooth prototyping board, loves it 👍

[@cbbios7804]

The project is great but if I wanted to program the same code of the program in an ATtiny85 but with Arduino would it work? And if the code of the program would be the same or it is modified for Arduino, I have no knowledge but I really want to learn.

[@RucaBan]

[@yupingliao4078]

Hello thank you＋👍 very much, but I don’t have an ISP adapter. I use an Arduino board to externally convert it to an ISP. In Clock, I choose 9.6MHZ to upload, and it is also successful. I have no problem testing MP3 and buttons

Can you make a tutorial how to make a bodyshell for a RC Car easy

[@TheDradge]

Isn't it pointless using the ATTiny13 when you can do all those switching functions with just the DFPlayer anyway?

[@diorama111]

I used the ATtiny13A to memorize the volume and the song number.

Sorry, for some reason the program exceeded the capacity and could not be written to the microcontroller, so I corrected the program.

[@nexuzinnovation-com]

diorama111 さん , is there a way to use volume rotational knob to control the volume up and down to the input pins IO_1 and IO_2 of DFPlayer ?

[@Scrogan]

They go into the ATtiny, so definitely. A rotary encoder with pullup resistors (maybe denouncing caps too) should easily be workable, so long as you change a bit of code. Probably be best to hook it up with an extra resistor or two in order for it to take up only a single pin alongside the repeat button, as is already being done with the current buttons. Could use the integrated pushbutton atop the encoder for the play/pause functionality too. Or you could use the button such that when the encoder is turned while the button is depressed, it changes songs (next, previous) instead of changing the volume. Or both. There’s also the option of fixing the output amplitude at max and using a volume potentiometer (perhaps with an amplifier IC) and just ditching the buttons.

[@nexuzinnovation-com]

@@Scrogan , thanks for the info sharing.

What is the battery you are using and what battery connector have you used can you give me a web link where to buy them

[@diorama111]

The battery is G-FORCE GH008(for H001) Li-Po 3.7V 80mAh. I bought it at Amazon Japan in 2018, but it was sold out. www.amazon.co.jp/%E3%82%B8%E3%83%BC%E3%83%95%E3%82%A9%E3%83%BC%E3%82%B9-80mAh-LiPo%E3%83%90%E3%83%83%E3%83%86%E3%83%AA%E3%83%BC-H001%E7%94%A8-GH008/dp/B06WGPVRKM I made the connector from 1.27mm pitch pins and pin sockets.
