Koj puas tau xav txog kev tsim koj tus kheej hais lus MP3 rau koj lub tsev kawm ntawv txoj kev ncaj ncees? Hauv txoj haujlwm no, peb yuav qhia koj ib qib zuj zus rau koj los tsim koj tus kheej hais lus thiab siv ob peb yam kev pab thiab muaj kev lom zem nrog koj cov phooj ywg.

Yog li, hauv txoj haujlwm no koj yuav kawm:

  • Kev ua haujlwm ntawm DFPlayer Mini MP3 module;
  • Tsim kom muaj kev tswj hwm yooj yim;
  • Solder koj daim npav tswj lub suab;
  • Tsim cov rooj plaub hais lus MDF.

Tam sim no, peb yuav pib ua ntu zus los ua ke ib kauj ruam zuj zus.

Khoom siv

  • 01 x JLCPCB Luam Ntawv Circuit Board
  • 04 x JST Connector 1x2
  • 01 x DFPlayer Mini

Kauj Ruam 1: DFPlayer Mini Module

DFPlayer Mini Module
DFPlayer Mini Module

DFPlayer Mini MP3 Player Rau Arduino yog qhov me me thiab tus nqi qis MP3 module nrog qhov yooj yim tso tawm ncaj qha rau tus hais lus. Tus qauv tuaj yeem siv ua qhov sawv ntsug ib leeg nrog lub roj teeb txuas, hais lus thiab thawb lub pob lossis siv ua ke nrog Arduino UNO lossis lwm yam nrog RX/TX lub peev xwm.

Cov hauv qab no yog qee qhov kev ua haujlwm ntawm DFPlayer Mini module

  • txhawb kev ntsuas tus qauv (kHz): 8/11.025/12/16/22.05/24/32/44.1/48
  • 24 -ntsis DAC tso tawm, txhawb rau ntau yam sib txawv 90dB, SNR txhawb 85dB
  • txhawb nqa FAT16, FAT32 cov ntaub ntawv kaw lus, txhawb nqa ntau tshaj 32G ntawm daim npav TF, txhawb 32G ntawm U disk, 64M bytes NORFLASH
  • ntau hom kev tswj hwm, I/O tswj hom, hom ua haujlwm, AD khawm tswj hom
  • tshaj tawm suab tos ua haujlwm, suab paj nruag tuaj yeem raug ncua. thaum tshaj tawm hauv cov nkauj txuas ntxiv mus
  • cov ntaub ntawv suab txheeb los ntawm daim nplaub tshev, txhawb nqa txog 100 daim nplaub tshev, txhua daim nplaub tshev tuaj yeem tuav txog 255 nkauj
  • 30 qib kho tau ntim, 6 -qib EQ kho tau.

DFPlayer Mini Module muaj ob peb tus pin rau kev ua haujlwm sib txawv. Txawm li cas los xij, hauv kab lus no peb yuav nthuav qhia koj kev tswj suab paj nruag nrog ob lub khawm.

Los ntawm ob lub khawm no nws yuav tuaj yeem ua cov nkauj thiab tswj lub ntim ntim, raws li qhia hauv qab no.

Kauj Ruam 2: Lub hauv paus Circuit Court ntawm DFPlayer Mini

Lub Circuit Court qhia saum toj no, yog lub hauv paus pib rau kev ua suab paj nruag tswj ntawm DFPlayer Mini ntaus ntawv. Raws li koj tuaj yeem pom, ob lub khawm tau siv los tswj lub ntim thiab cov nkauj.

Lub pob txuas nrog IO1 tus pin yuav raug siv los ua suab paj nruag yav dhau los thiab tseem yuav txo qhov ntim ntawm zaj nkauj. Txhawm rau txo lub suab nrov, nws yuav tsum tuav lub pob kom ntev dua 500 ms. Txoj kev no, lub ntim yuav raug txo.

Lub pob txuas nrog IO2 tus pin, ntawm qhov tod tes, yuav raug siv los ua si kab ntawv tom ntej thiab tseem nce qhov ntim ntawm zaj nkauj. Rau qhov no, tib txoj kev txo cov suab paj nruag yuav tsum tau ua.

Los ntawm kab lus no, peb yuav txuas tus neeg hais lus rau tus pin SPK_1 thiab SPK_2. Tom qab ntawd, peb yuav muab peb cov khoom siv hluav taws xob ntawm 5V ntawm GND thiab VCC tus pin, raws li qhia hauv daim duab hluav taws xob hluav taws xob.

Txhua qhov txuas txuas rau DFPlayer Mini module tau qhia hauv daim duab saum toj no.

Tam sim no, peb yuav nthuav qhia kev tsim kho lub rooj tsav xwm luam tawm ntawm MP3 suab lub thawv

Kauj Ruam 3: Lub Rooj Tsav Xwm ntawm SoundBox MP3 Player

Hauv qhov phiaj xwm phiaj xwm phiaj xwm luam tawm - JLCPCB, tau siv 4 JST Txuas. Lub C1 txuas tau siv los txuas lub zog hluav taws xob, C2 yuav siv los txuas tus hais lus, thiab C3 thiab C4 yuav raug siv los txuas lub pob ntawm kev tswj cov kab thiab qib nkauj ntawm cov nkauj.

Los ntawm lub Circuit Court, tau teeb tsa lub rooj tsav xwm luam tawm ntawm txoj haujlwm no.

Cov Luam Luam Circuit Board tau nthuav tawm hauv cov theem hauv qab no.

Kauj Ruam 4: Luam Circuit Board Board ntawm MP3 SoundBox

Luam tawm Circuit Board ntawm MP3 SoundBox

Los ntawm cov txheej txheem hluav taws xob nthuav tawm hauv cov kauj ruam dhau los, peb tsim cov ntawv luam tawm Circuit Circuit board no.

PCB no yooj yim heev thiab muaj ib txheej. Ib qho ntxiv, tau siv 4 JST Txuas thiab DFPlayer Mini los ua nkauj.

Qhov txiaj ntsig tau nthuav tawm hauv daim duab saum toj no thiab PCB tuaj yeem tau txais hauv JLCPCB rau $ 2 - 10 PCBs.

Tom qab tsim PCB, tau tsim cov ntaub ntawv hluav taws xob. Cov ntaub ntawv tau tsim los khaws lub Circuit Court thiab teeb tsa cov nyees khawm ntawm kev tswj hwm ntawm MP3 Sound Box.

Cov ntaub ntawv yuav raug nthuav tawm hauv cov kauj ruam tom ntej.

Kauj Ruam 5: Tus Qauv ntawm SoundBox Case

Hauv seem, koj yuav nkag mus saib cov ntaub ntawv ntawm rooj plaub lub suab. Raws li tuaj yeem pom saum toj no, rooj plaub muaj cov duab plaub thiab cov ntawv rau laser txiav raug tso cai, ib yam nkaus.

Raws li pom tau, peb muaj ob lub qhov. Txhua lub qhov yog tsim los txhim kho cov tswj khawm ntawm cov nkauj. Lub thawv tau teeb tsa los ntawm kev sib koom tes ntiv tes thiab qhov txiaj ntsig tau nthuav tawm hauv daim duab ntawm sab laug.

Tom qab sib dhos lub thawv tsim thiab koom nrog ntu nrog cov kua nplaum, peb yuav tsum sau cov nkauj ntawm daim npav nco. Cov txheej txheem no tau nthuav tawm hauv qab no.

Kauj Ruam 6: Sau Cov Nkauj hauv SD Card

Sau nkauj hauv SD Card
Sau nkauj hauv SD Card

Txhawm rau sau koj cov nkauj hauv SD Card, txuas koj daim npav SD hauv koj lub computer thiab hloov cov nkauj. Tom qab qhov no, txuas koj daim npav SD hauv koj DFPlayer Mini.

Thaum kawg, kaw koj lub npov thiab muaj kev lom zem mloog koj cov nkauj.

Kauj Ruam 7: Kev lees paub

Ua tsaug JLCPCB los muab PCB Arduino Compatible Board Open Source Project los tsim kab lus no.
