Kauj Ruam 1: Dab Tsi DF Mini Player MP3 Module

DFMini Player module yog lub tshuab ua suab paj nruag me me, qis nqi thiab lub zog qis uas muaj lub hom phiaj rov ua suab nrov khaws cia rau ntawm daim npav nco.

Raws li qhov no, tus qauv tuaj yeem tswj tau ntawm tus kheej ib leeg, uas yog, hauv hom no, yuav tsuas yog DFMini module, roj teeb rau lub zog, tus hais lus, khawm kom tswj nws thiab SD Card nrog cov nkauj. Lwm txoj hauv kev los tswj nws yog siv Arduino lossis lwm lub cuab yeej tswj.

Piv txwv li, Arduino yuav xa cov lus txib los ntawm kev sib txuas lus txuas nrog DFMini Player Module. DFMini Player module tau qhia hauv daim duab 1.

Txhawm rau tswj nws, nws yog ib qho tseem ceeb uas yuav tsum tau siv lub hauv paus ib leeg zuj zus. Lub voj voog no tau qhia hauv daim duab 2.

Ob lub nyees khawm qhia hauv kab lus saum toj no tau siv los hloov cov nkauj thiab tswj lub suab nrov. Qhov khawm txuas nrog tus pin IO1 yog siv los mus rau yav dhau los thiab txo lub ntim. Nrog qhov kov lub kaw lus nrawm rov qab rau zaj nkauj dhau los, txawm li cas los xij, yog tias koj nias lub pob ntau dua 1 thib ob, lub kaw lus yuav txo qhov ntim ntawm zaj nkauj.

Lub pob txuas nrog tus pin IO2 tau siv los mus rau qhov txuas ntxiv thiab nce ntim. Nrog kev kov lub kaw lus nrawm mus rau zaj nkauj tom ntej, txawm li cas los xij, yog tias koj nias lub pob ntau dua 1 thib ob, lub kaw lus yuav ua rau lub suab nkauj nce ntxiv.

Kauj ruam 2:

Hauv txoj hauv kev ib leeg, cov nkauj yuav tsum tau khaws tseg ntawm daim npav nco, raws li qhia hauv daim duab 3.

Txoj kev no, txhua lub sij hawm cov nyees khawm raug nias, lub kaw lus yuav ua si txhua zaj nkauj kom nce lossis nqis qis. Txawm li cas los xij, thaum siv Arduino lossis lwm lub cuab yeej tswj hwm, peb yuav tsum hloov kho txoj kev teeb tsa cov suab paj nruag cov ntaub ntawv ntawm SD Card.

Tam sim no, kuv yuav piav qhia yuav ua li cas tswj DFMini Player siv Arduino los ntawm kev sib txuas lus txuas.

Kauj Ruam 3: Tswj DFMini Player Nrog Arduino

Hauv cov kauj ruam no, kev tswj ntim, kev tswj hwm ntau yam, cov lus txib sib npaug thiab lwm yam yuav raug xa los ntawm Arduino.

Arduino yuav tsum sib txuas lus ntawm cov lej nrog DFMini Player thiab xa cov lus txib tswj.

Cov txheej txheem hluav taws xob ntawm kev tswj hluav taws xob tau qhia hauv daim duab 4.

Ua ntej, peb yuav tsum sib sau ua ke cov kab lus pom hauv daim duab hauv qab no. Tom qab sib dhos cov Circuit no, koj yuav tsum ntxiv cov nkauj ntawm koj daim npav nco. Hauv qib no, cov nkauj yuav tsum tau hloov pauv ua 01, 02, 03, piv txwv.

Koj tsis tuaj yeem tso cov nkauj nrog lawv cov npe, vim yuav muaj teeb meem thaum Arduino xa cov lus txib kom ua tiav txoj haujlwm tshwj xeeb. Yog li, koj yuav tsum teeb tsa raws li qhia hauv qab no.

Kauj ruam 4:

Tom qab npe cov ntaub ntawv, sau cov cai hauv qab no ntawm koj Arduino.

// Tos rau cov ntaub ntawv nkag ntawm serialwhile (Serial.available ()> 0) {hais kom ua = Serial.read (); if ((command> = '1') && (command <= '9')) {Serial.print ("Luam dua nkauj"); Serial.println (hais kom ua); hais kom ua = hais kom ua - 48; myDFPlayer.play (hais kom ua); menu_opcoes (); cov. } // Luam tawm // Nres yog (hais kom ua == 's') {myDFPlayer.stop (); Serial.println ("Music Stopped!"); menu_opcoes (); cov. } // Pausa/Txuas mus rau musica yog (hais kom ua == 'p') {pausa =! Pausa; yog (pausa == 0) {Serial.println ("Mus ntxiv …"); myDFPlayer.start (); } yog (pausa == 1) {Serial.println ("Music Paused!"); myDFPlayer.pause (); } menu_opcoes (); cov. }

// Nce ntim

yog (hais kom == '+') {myDFPlayer.volumeUp (); Serial.print ("Tam sim no ntim:"); Serial.println (myDFPlayer.readVolume ()); menu_opcoes (); cov. } yog (hais kom ua == '') {myDFPlayer.next (); Serial.println ("tom ntej:"); Serial.print ("Tam sim no khiav:"); Serial.println (myDFPlayer.readCurrentFileNumber ()+1); menu_opcoes (); cov. } // Txo ntim yog tias (hais kom ua == '-') {myDFPlayer.volumeDown (); Serial.print ("Ntim tam sim no:"); Serial.println (myDFPlayer.readVolume ()); menu_opcoes (); cov. }}} void menu_opcoes () {Serial.println (); Serial.println (F ("=========================================================== ====================================================================== ===================================== ")); Serial.println (F ("Commands:")); Serial.println (F ("[1-3] Txhawm rau xaiv cov ntawv MP3")); Serial.println (F ("[s] nres kev tsim tawm")); Serial.println (F ("[p] ncua/txuas ntxiv nkauj")); Serial.println (F ("[+ lossis -] nce lossis txo qhov ntim")); Serial.println (F (" mus tom ntej lossis rov qab taug qab")); Serial.println (); Serial.println (F ("=========================================================== ====================================================================== ==================================== ")); }

Cov cai uas tau hais los saum no yog qhov yooj yim heev thiab yuav pab koj xaiv cov nkauj los ntawm nws tus lej, nres, ncua, tswj lub ntim thiab hla txoj kab.

Kev tswj suab paj nruag suav nrog xa cov ntaub ntawv los ntawm Arduino IDE cov ntawv rau peb Arduino pawg thawj coj. Thaum xub thawj, cov txheej txheem ua rau kev teeb tsa hauv kev teeb tsa thiab txheeb xyuas yog tias SD Card tau muab tso rau hauv qhov qauv.

Yog tias nws tsis tau tso, lub kaw lus nthuav tawm cov lus ceeb toom rau tus neeg siv.

Ib qho ntxiv, lub kaw lus qhia cov lus nrog cov txheej txheem teeb tsa kev teeb tsa.

teeb tsa tsis muaj dab tsi () {// Comunicacao serial com o modulo mySoftwareSerial.begin (9600); // Inicializa serial do Arduino Serial.begin (115200); // Verifica se o modulo esta respondendo e se o // cartao SD foi encontrado Serial.println (); Serial.println (F ("DFRobot DFPlayer Mini")); Serial.println (F ("Pib DFPlayer module … Tos!")); yog (! myDFPlayer.begin (mySoftwareSerial)) {Serial.println (F ("Tsis tau pib ua:")); Serial.println (F ("1. Txheeb xyuas DFPlayer Mini sib txuas")); Serial.println (F ("2. Ntxig daim npav SD")); thaum (muaj tseeb); } Serial.println (); Serial.println (F ("DFPlayer Mini module pib ua!")); // Definicoes iniciais myDFPlayer.setTimeOut (500); // Timeout serial 500ms myDFPlayer.volume (5); // Ntim 5 myDFPlayer. EQ (0); // Equalizacao ib txwm menu_opcoes (); }

Yog tias daim npav nco tau ntxig, cov cai ntws yuav nkag mus rau lub voj ua haujlwm.

void loop () {// Tos rau cov ntaub ntawv nkag los ntawm cov lej thaum (Serial.available ()> 0) {hais kom ua = Serial.read (); if ((command> = '1') && (command <= '3')) {Serial.print ("Luam dua nkauj"); Serial.println (hais kom ua); hais kom ua = hais kom ua - 48; myDFPlayer.play (hais kom ua); menu_opcoes (); cov. } // Luam tawm // Nres yog (hais kom ua == 's') {myDFPlayer.stop (); Serial.println ("Music Stopped!"); menu_opcoes (); cov. } // Pausa/Txuas mus rau musica yog (hais kom ua == 'p') {pausa =! Pausa; yog (pausa == 0) {Serial.println ("Mus ntxiv …"); myDFPlayer.start (); } yog (pausa == 1) {Serial.println ("Music Paused!"); myDFPlayer.pause (); } menu_opcoes (); }

// Nce ntim

yog (hais kom == '+') {myDFPlayer.volumeUp (); Serial.print ("Tam sim no ntim:"); Serial.println (myDFPlayer.readVolume ()); menu_opcoes (); cov. } yog (hais kom ua == '') {myDFPlayer.next (); Serial.println ("tom ntej:"); Serial.print ("Tam sim no khiav:"); Serial.println (myDFPlayer.readCurrentFileNumber ()+1); menu_opcoes (); cov. } // Txo ntim yog tias (hais kom ua == '-') {myDFPlayer.volumeDown (); Serial.print ("Ntim tam sim no:"); Serial.println (myDFPlayer.readVolume ()); menu_opcoes (); cov. }}}

Tus neeg siv tuaj yeem xa cov cim tswj hauv qab no:

Zauv 1 txog 3: Xaiv zaj nkauj los ua si;

• Tsab ntawv s: Nres zaj nkauj; Tsab ntawv p: ncua zaj nkauj;
• Xa qhov + kos npe: Ua kom lub suab nkauj nce ntxiv;
• Xa lub - teeb liab: Txo qhov ntim nkauj;
• Xa lub teeb liab <: Xaiv zaj nkauj dhau los;
• Xa lub teeb liab>: Xaiv zaj nkauj tom ntej;

Los ntawm cov cim no, cov tsiaj ntawv, thiab tus lej, Arduino yuav tau txais lawv ntawm cov lej thiab yuav tswj cov nkauj kom ua si.

Txhua qhov xwm txheej tau nthuav tawm hauv qab no thiab sab hauv, nrog nws cov lus txib.

if ((command> = '1') && (command <= '3')) {Serial.print ("Luam dua nkauj"); Serial.println (hais kom ua); hais kom ua = hais kom ua - 48; myDFPlayer.play (hais kom ua); menu_opcoes (); cov. } // Luam tawm // Nres yog (hais kom ua == 's') {myDFPlayer.stop (); Serial.println ("Music Stopped!"); menu_opcoes (); cov. } // Pausa/Txuas mus rau musica yog (hais kom ua == 'p') {pausa =! Pausa; yog (pausa == 0) {Serial.println ("Mus ntxiv …"); myDFPlayer.start (); } yog (pausa == 1) {Serial.println ("Music Paused!"); myDFPlayer.pause (); } menu_opcoes (); }

// Nce ntim

yog (hais kom == '+') {myDFPlayer.volumeUp (); Serial.print ("Tam sim no ntim:"); Serial.println (myDFPlayer.readVolume ()); menu_opcoes (); cov. } yog (hais kom ua == '') {myDFPlayer.next (); Serial.println ("tom ntej:"); Serial.print ("Tam sim no khiav:"); Serial.println (myDFPlayer.readCurrentFileNumber ()+1); menu_opcoes (); cov. } // Txo ntim yog (hais kom ua == '-') {myDFPlayer.volumeDown (); Serial.print ("Ntim tam sim no:"); Serial.println (myDFPlayer.readVolume ()); menu_opcoes (); cov. }}

Yog li, yog tias koj ua ntawv thov txhua qib uas tau nthuav tawm, koj muaj peev xwm kawm tau:

• Kev pib ua haujlwm yooj yim ntawm DFMini Player MP3;
• Lub koom haum thiab teeb tsa cov ntaub ntawv suab ntawm daim npav nco;
• Kev tswj suab paj nruas nrog Arduino. From tus lej no, koj tuaj yeem txhim kho lwm txoj haujlwm uas xav tau siv lub suab ua lub luag haujlwm.
