Kauj ruam 8:

Cov npe chaw nyob no yog siv los teeb tsa tus qauv kev ua haujlwm. Piv txwv, saib qhov chaw sau npe hauv qab no.

#txhais CMD_PLAY_W_INDEX 0X03

Chaw nyob 0x03 tau hais nrog lub npe CMD_PLAY_W_INDEX. Nws tau siv los ua ib zaj nkauj los ntawm nws tus lej, uas yog, koj nkag mus rau tus lej ntawm lub suab thiab nws yuav raug ntaus.

Nws yuav nrog cov txiaj ntsig no uas peb yuav siv lawv thiab teeb tsa kev ua haujlwm ntawm peb tes num.

Tom qab koj tau piav qhia ntau qhov chaw nyob uas yuav siv, peb yuav nkag mus rau teeb tsa kev teeb tsa thiab teeb tsa tus pin thiab kev sib txuas lus txuas rau peb qhov haujlwm.

Kauj Ruam 9: Lub Void Setup () Function

Tom ntej no, pom qhov tsis muaj teeb tsa teeb tsa ua haujlwm. Kuv tau ua txhua qhov teeb tsa ntawm lub khawm khawm, kev sib txuas lus ntawm MP3 module, thiab kev pib ua daim npav hauv MP3.

void teeb tsa ()

{Serial.begin (9600); mp3.begin (9600); ncua (500); rau (tus pin = 8; tus pin <13; tus pin ++) {pinMode (tus pin, INPUT); } sendCommand (CMD_SEL_DEV, 0, DEV_TF); ncua (500); }

Kuv pib qhov kev sib txuas lus txuas mus luam tawm cov ntaub ntawv ntawm lub khoos phis tawj cov ntawv xov xwm thiab tom qab ntawd peb pib qhov kev sib txuas lus txuas mus los ntawm qhov khoom mp3.

Serial.begin (9600);

mp3.begin (9600); ncua (500);

Lub mp3 module yog tswj los ntawm cov lus txib tau txais los ntawm Arduino cov ntawv. Hauv cov txheej txheem no, peb siv SoftwareSerial lub tsev qiv ntawv thiab ua raws kab lus ntawm Arduino cov lej digital.

Yog li, koj yuav tuaj yeem siv Arduino los tswj lub MP3 module los ntawm cov lus txib xa mus rau nws.

Ib qho ntxiv, peb tau teeb tsa lub koob ntawm cov lej digital thiab pib ua haujlwm ntawm MP3 Card module

rau (tus pin = 8; tus pin <13; tus pin ++) {pinMode (tus pin, INPUT); } sendCommand (CMD_SEL_DEV, 0, DEV_TF); ncua (500);

Tom qab ua qhov teeb tsa, peb yuav tsum mus rau lub laj thawj tseem ceeb hauv qhov tsis muaj dab tsi ua haujlwm.

Kauj Ruam 10: Lub luag haujlwm tseem ceeb Void Loop ()

Cov cai yog qhov yooj yim heev thiab tag nrho cov qauv muaj tswv yim tau nthuav tawm hauv qab no. Hauv qab no, kuv yuav piav qhia rau koj ua tiav logic ntawm lub luag haujlwm tseem ceeb.

void lub voj ()

{pin = 8; randomSeed (analogRead (A0)); numero = random (8, 12); SortNumber = tooj; numero = numero - 7; Serial.println (tus lej); sendCommand (0x03, 0, numero); ncua (1000); ua {khawm = digitalRead (tus pin); Serial.println (khawm); tus pin ++; yog (tus pin> 13) {tus pin = 8; } Serial.println ("Varrendo …"); Serial.println (tus pin); // ncua (1000); } thaum (khawm! = 1); Serial.println ("Saiu …"); yog (khawm == 1 && (pin-1)! = sortNumber) {sendCommand (0x03, 0, 6); ncua (3000); } yog (khawm == 1 && (pin-1) == SortNumber) {sendCommand (0x03, 0, 7); ncua (3000); } // Txheeb xyuas cov lus teb. yog (mp3.available ()) {Serial.println (decodeMP3Answer ()); } ncua (100); //Serial.println("Tocando musica … "); }

Ntawm txhua qhov pib ntawm lub voj kev ua haujlwm, peb yuav tsim tus nqi tshiab ntawm 8 thiab 12 los tsim lub suab ntawm tus vowel. Tus nqi ntawm 8 txog 12 hais txog tus lej digital ntawm tus vowel.

Cov cai rau kev tsim tus lej tsis raug yog qhia hauv qab no.

pin = 8;

randomSeed (analogRead (A0)); numero = random (8, 12); SortNumber = tooj;

Ib qho ntxiv, peb rho 7 los ntawm tus lej kos ntawm 8 thiab 12. Qhov no yuav tso cai rau peb taw tes rau txoj haujlwm ntawm 1 txog 5 ntawm cov nkauj kaw rau ntawm daim npav nco.

numero = numero - 7;

Tom qab ntawd, Kuv rov tsim dua lub suab ntawm lub vowel kos ntawm kab hauv qab no.

sendCommand (0x03, 0, numero);

ncua (1000);

Tam sim no lub sijhawm tseem ceeb tau los txog: lub sijhawm uas peb yuav mus nyeem lub pob nyem los ntawm tus menyuam. Tshooj cai tau nthuav tawm hauv qab no.

ua

{khawm = digitalRead (tus pin); Serial.println (khawm); tus pin ++; yog (tus pin> 13) {tus pin = 8; } Serial.println ("Varrendo …"); Serial.println (tus pin); // ncua (1000); } thaum (khawm! = 1);

Lub voj no yuav ua tiav kom txog thaum tus neeg siv nias lub pob. Lub voj tso cai rau koj luam theej duab 5 tus lej digital thiab lub sijhawm tus menyuam nias ib lub khawm, nws yuav tawm ntawm lub voj thiab tshawb xyuas yog tias tus menyuam tau teb raug lawm.

Koj yuav ua qhov pov thawj siv tus lej hauv qab no.

yog (khawm == 1 && (pin-1)! = SortNumber)

{xaCommand (0x03, 0, 6); ncua (3000); } yog (khawm == 1 && (pin-1) == SortNumber) {sendCommand (0x03, 0, 7); ncua (3000); }

Thawj qhov xwm txheej yuav raug ua tiav thaum tus neeg siv ua yuam kev vim tias lub pob tau raug nias thiab qhov txiaj ntsig ntawm tus lej tau txawv ntawm tus pin kos (SortNumber).

Txij ntawm no mus, koj yuav tsum ua cov lus txib hauv qab no.

sendCommand (0x03, 0, 6);

ncua (3000);

Cov lus txib no yog siv los ua kom lub suab tsis raug. Thaum kawg, peb muaj qhov xwm txheej thib ob uas yuav siv los tshuaj xyuas seb tus menyuam puas raug.

yog (khawm == 1 && (pin-1) == SortNumber)

{xaCommand (0x03, 0, 7); ncua (3000); }

Kauj ruam 11:

Yog tias lub pob tau nyem thiab tus lej digital uas tau nias yog zoo ib yam li tus pin kos, lub kaw lus yuav ua kom lub suab teb raug.

Raws li kuv piav qhia rau koj, cov cai no yooj yim heev thiab yuav pab txhua tus menyuam txhim kho lawv txoj kev paub ntawm vowels los ntawm kev ua si nrog Arduino.

Hauv daim duab saum toj no lub thawv suab tau ua tiav zaj nkauj khaws tseg hauv SD Card ntawm MP3 Module YX5300.

Kauj Ruam 12: Xaus
