Hauv cov lus qhia no peb yuav kawm paub yuav ua li cas rub tawm mp3 cov ntaub ntawv nrog arduino yam tsis siv lub kaw lus suab, ntawm no peb yuav siv PCM lub tsev qiv ntawv rau Arduino uas ua haujlwm 16 ntsis PCM ntawm 8kHZ zaus yog li cia ua qhov no.

Kauj Ruam 1: Sau Koj Cov Cheeb Tsam

YUAV TSUM MUAJ: YUAV TSUM 120:

//////////////////////////////////////////////////////

yog li txhawm rau ua qhov no peb xav tau ob peb yam ua tau zoo Ib qho Arduino & tom qab ntawd tus neeg hais lus 0.5w txog 10 w txhua tus neeg hais lus yuav ua txoj haujlwm tom qab ntawd koj yuav tsum yuav lub transistor rau kev ua kom nrov yog tias koj tus neeg hais lus siab dua 0.5w raws li kuv tau 3 w yog li kuv tau siv TIP 120 transistor dor ua kom nrov dua lub suab koj tuaj yeem siv txhua lub suab nrov ntxiv.

Kauj ruam 2: Kev sib txuas

Cov kev sib txuas yog yooj yim tiag tiag yog tias koj siv tus neeg hais lus 0.5watt txuas ncaj qha txuas rau +tus pin ntawm tus hais lus rau tus lej digital 11 ntawm Arduino & -ve tus pin ntawm tus hais lus rau gnd & yog tias siv 3 watt hais lus ces siv lub taub hau 120 transistor & txuas 11 ntawm Arduino mus rau lub hauv paus ntawm transistor thiab -ve tus pin ntawm tus hais lus rau tus sau ntawm transistor & emitter ntawm transistor rau gnd pin ntawm Arduino.

IIf muaj teeb meem nrog kev txuas txuas video rau kev pab.

Kauj Ruam 3: Rub Cov Ntaub Ntawv Yuav Tsum Tau

Txhawm rau ua qhov no koj yuav xav tau ob peb cov ntaub ntawv ua ntej ntawm txhua daim ntawv PCM.zip ua si PCM suab los ntawm arduino.

THEN peb yuav xav tau Audacity software los hloov lub suab mp3 ib txwm rau 16bit PCM 8hkz audio

& Thaum kawg peb xav tau software encoder los kho lub suab ntawd rau hauv cov ntaub ntawv uas peb tuaj yeem muab tso rau hauv cov cai.

Kauj Ruam 4: Npaj Suab & Hloov Nws Ua Cov Ntaub Ntawv

cov kauj ruam tseem ceeb yog npaj cov ntaub ntawv audio.so thawj zaug peb yuav xav tau cov ntaub ntawv mp3 txawm tias koj kaw ib los lossis tau txais ib qho los ntawm txhua qhov chaw ces qhib cov ntawv ntawd rau hauv Audacity thiab & nyem rau ntawm hom ntawv tom qab ntawd xaiv 16 ntsis pcm ces nqes mus & xaiv zaus ntawm lub suab mus rau 8000hz & xa lub suab zoo li mp3.

Tom qab ntawd qhib qhib lub suab software & taw mus rau cov ntaub ntawv audio peb tau tsim los ntawm kev muaj peev xwm ces koj yuav tau txais cov lus suab theej rau daim ntawv teev npe ua tiav.

Kauj Ruam 5: Coding Tshooj

yog li ntu tom ntej yog coding ib feem, yog li koj rub tawm Arduin mp3.zip cov ntaub ntawv uas muaj PCM.zip cov ntaub ntawv yog li ntxiv PCM.zip cov ntaub ntawv no ua lub tsev qiv ntawv rau arduino & tom qab ntawd qhib qhov ua piv txwv muaj nyob hauv PCM lub tsev qiv ntawv ntawd, & nyob rau hauv qhov kos duab koj yuav tsum hloov kab thib ob ntawm cov cai hauv tus qauv arrray uas yog hom programem koj yuav tsum tshem tawm txhua cov ntaub ntawv hauv qhov ntawd aray & paste cov ntaub ntawv uas tau theej rau hauv ntawv los ntawm encode audio software.

Kauj Ruam 6: Tshaj Tawm Txoj Cai

yog li thaum kawg peb cov cai tau npaj tiav yog li rub nws mus rau arduino & koj yuav hnov koj lub suab kaw los ntawm tus hais lus, txaus siab rau nws & yog tias koj muaj teeb meem lossis xav txog qhov no hauv qhov tob tsuas yog xa cov vis dis aus.

Ua tsaug.
