2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Hauv cov lus qhia no koj yuav kawm paub yuav ua li cas thiaj ua rau koj tus kheej DIY hnab tshos suab paj nruag player nrog ncua kev ua si hla thiab tej zaum lwm cov yam ntxwv siv siv arduino pro mini lossis arduino nano.

Kauj Ruam 1: Cov Cheeb Tsam Xav Tau

Txhawm rau ua qhov no koj yuav xav tau ob peb yam khoom muab hauv cov npe hauv qab no:

1. Arduino pro mini lossis arduino nano

2. FTDI (yog tias koj siv arduino pro mini)

3. 5v Boost (tsuas yog tias koj daim npav daim npav SD yog 5v sib xws lwm qhov ntse yog tias koj muaj 3.3v micro sd daim npav adapter ces koj tuaj yeem hla qhov no thiab siv koj lub zog daim npav SD hloov siv vcc ntawm arduino pro mini lossis nano ncaj qha)

4. Li-ion roj teeb

5. Micro sd card adapter

6. Ib daim npav micro sd

7. Ib lub sijhawm thawb khawm

8. Ib qho qhib/tua hloov

9. Txhua rooj plaub los tuav tag nrho cov khoom siv

Kauj ruam 2: Schematic ntawm Circuit

Ua rau koj lub Circuit Court raws li qhia hauv daim duab ntawm lub khob cij los yog ncaj qha muab cov xov hlau txuas rau.

(siv 2.2uF capacitor nruab nrab ntawm hauv av thiab teeb liab tus pin ntawm 3.5mm jack ua kom lub suab zoo rau lub suab zoo dua)

Kauj Ruam 3: Cov Cai thiab Cov Tsev Qiv Ntawv

Ua ntej rub tawm cov cai kom ntseeg tau tias koj tau teeb tsa cov tsev qiv ntawv xav tau. rau nruab ces cov theem tau muab hauv qab no:

Txuas rau lub tsev qiv ntawv:

github.com/TMRh20/TMRpcm

github.com/mathertel/OneButton

Cov kauj ruam rau nruab tsev qiv ntawv:

1. Rub lub tsev qiv ntawv.

2. Qhib koj Arduino IDE.

3. Nyem qhov kos duab xaiv ntawm cov ntawv qhia zaub mov.

4. Nyem nrog cov tsev qiv ntawv xaiv thiab tom qab ntawv xaiv "Ntxiv. ZIP tsev qiv ntawv".

5. Tom qab ntawv mus rau daim nplaub tshev uas koj tau rub lub tsev qiv ntawv.

6. Nyem rau zip file.

7. Tom qab ob peb feeb koj yuav tau txais cov lus hauv koj li IDE lub tsev qiv ntawv tau suav nrog.

Tam sim no koj tuaj yeem COMPILE cov cai

Kauj ruam 4: Hloov Mp3 Music rau WAV File

Lub tsev qiv ntawv tmrpcm tuaj yeem ua tiav. WAV cov ntaub ntawv suab paj nruag yog li koj yuav tsum hloov koj cov nkauj mp3 ua ntaub ntawv thov rau. WAV cov ntaub ntawv.

Qhov no yuav siv ob peb feeb. Tsuas yog ua raws cov theem qhia:

1. Qhib qhov txuas "https://audio.online-convert.com/convert-to-wav"

2. Tam sim no upload cov nkauj mp3.

3. Ua qhov kev xaiv teeb tsa raws li qhia hauv daim duab 1.

4. Tam sim no nyem pib hloov dua siab tshiab khawm.

5. Tam sim no koj tuaj yeem rub tawm cov ntawv.

6. Qhib daim nplaub tshev uas nws tau rub tawm thiab hloov npe mus rau tus lej 1

7. Yog tias koj xav ntxiv cov ntawv ntxiv tom ntej no npe cov ntawv txuas ua ke tus lej tom ntej raws li qhia hauv daim duab hauv qab no

8. Tam sim no muab cov ntawv no tso rau hauv koj daim npav SD.

9. Nruab qhov no rau koj lub micro SD adapter.

Kauj ruam 5:

Kauj Ruam 6: Tam sim no tig lub CIRCUIT rau…. Thiab txaus siab rau koj tus kheej lub suab paj nruag

Xav tias yuav nug ib qho lus nug, Kuv yuav sim daws nws ASAP.
