Cov lus qhia no qhia koj kom nkag siab txog kev thim rov qab engineering, txheeb xyuas cov ntaub ntawv thiab tsim cov khoom tshiab nrog cov ntaub ntawv no.
Kauj ruam 1: Nrhiav Tawm Pinouts
Txhawm rau nkag siab txoj haujlwm ua haujlwm ntawm chaw nres tsheb sensor, Kuv xav tau kom qhia meej cov ntaub ntawv tus pin. Tom qab ntawd kuv ntsuas cov ntsuas hluav taws xob nrog cov ntsuas ntsuas thiab pom tias muaj 3-tus pin txuas nruab nrab ntawm Lub Zeem Muag thiab chav tsev tseem ceeb, kab thib 4 tsis ua haujlwm uas yog:
- GND - LOJ
- VCC - RED
- DATA - DAWB
Kuv txuas ib qho dub nrog hauv av thiab dawb ib qho rau Channel 1 ntawm kev ntsuas tus lej.
Kauj Ruam 2: Txuas Kev Tshawb Fawb Logic & Tshawb Fawb Txoj Cai Ua Haujlwm
Tom qab ua haujlwm rau ib lub lim tiam ntawm kev nkag siab lub ntsiab lus ntawm cov khoom, Kuv pom tias thawj byte nruab nrab qhov nrug nyob rau hauv daim ntawv ntawm kev thim rov qab ntawm txhua qhov me ntsis, tom qab 4 cov khoom yog sensor id thiab kawg 4 khoom yog cov khoom nres.
Kauj Ruam 3: Ntxiv Qhov Tshiab "Hais Lus" Yav Tom Ntej Nrog Siv Arduino & Serial Mp3 Player Module
Kuv ntsuas qhov ntev ntawm Pib Pib Teeb Meem, muaj tswv yim 1 thiab muaj tswv yim 0 hauv vib nas this me. Nws tau pab kuv faib lawv ua peb daim ntawv no. Tsis tas li kuv txuas cov npav tsheb mus rau arduino nano cuam tshuam tus pin (D2).
Tom qab kuv rho tawm cov ntaub ntawv, kuv tau sau qhov program uas tuaj yeem xa cov lus txib mus rau cov neeg siv mp3 hauv xov tooj ntawm uart. Kuv siv softwareserial D8 D9 ntawm arduino.
Arduino Nano txuas nyob ntawm no
Mp3 module txuas ntawm no
Arduino Nano Code nyob hauv qhov txuas
Kauj Ruam 4: Cov Ntaub Ntawv Hauv Microsd Card (Mp3 Player)
01 / 001.mp3 nws cov lus txais tos
thaum koj hloov koj lub tsheb mus rau lub iav rov qab, koj yuav ntsib nrog qhov no.
lwm cov ntaub ntawv zoo li:
- 01 / 002.mp3 10-20 cm.
- 01 / 003.mp3 20-30 cm.
- 01 / 004.mp3 30-40 cm.
- 01 / 005.mp3 40-50 cm.
- 01 / 006.mp3 50-60 cm.

Kauj Ruam 5: Tsim Circuit Court thiab PCB
Kuv siv www.easyeda.com los tsim kuv lub Circuit Court thiab tsim nws cov pcb.
koj tuaj yeem nkag mus rau kuv qhov project los ntawm no
Kauj Ruam 6: Kev xaj JST XH Cov Txuas thiab Tus Hais Lus
Txhawm rau siv tib qhov txuas ntawm qhov chaw nres tsheb sensor kuv xaj 2.5 4-pin 3S1P Tshuav Nyiaj Txiag Silicon Cable Hlau JST XH Txuas Txuas Txuas Txuas los ntawm qhov txuas no thiab tus hais lus los ntawm qhov txuas no
Kauj Ruam 7: Qhov Kawg: Soldering PCB
Nws ua haujlwm txig!:)
