2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Cov lus qhia no qhia yuav ua li cas thiaj li ua kom WiFi pib hloov kho daim duab duab ntxiv nrog rau cov menyuam yaus daim npav daim npav ua lag luam.

Kauj Ruam 1: Vim Li Cas Daim Duab Duab rau Menyuam?

Kuv tus menyuam nyiam ua si txhua qhov nyem xws li fidget, Portable WiFi Analyzer, TV remote, iPhone home button (^o^);

Kuv tus menyuam nyiam saib cov duab ntawm nws tus kheej, nws ib txwm nqa lub iPad lossis txawb rau peb thiab nug kom pom cov duab (^_^) a;

Kuv tus menyuam tsis nyiam flashcard (~ _ ~).

Yuav ua li cas thiaj tsim tau daim duab me me digital uas tuaj yeem pib rub tawm cov duab tshiab, tib lub sijhawm nws yuav cia li tso saib flashcard "lag luam"?

Nws zoo li nthuav, cia peb sim nws!

Kauj ruam 2: Kev npaj

Roj teeb Powered IoT Device

Flashcard

Muaj ntau yam flashcard ntawm lub vev xaib, ntawm no yog qhov kuv siv hauv qhov piv txwv no:

busyteacher.org/24109-printable-alphabet-fl…

Kauj Ruam 3: Tsim

Qhov pib hloov kho duab album tau muab cais ua 2 ntu:

Photo neeg rau zaub mov

Nws lub hom phiaj khaws cov duab tshiab, hloov pauv, qoob loo thiab tom qab ntawd ua haujlwm rau IoT ntaus ntawv.

Hauv qhov kev qhia no kuv siv Node.js HTTP server nrog lub tsev qiv ntawv ntse. Tsuas yog rub daim duab tshiab rau hauv daim nplaub tshev duab, nws pib hloov pauv thiab qoob loo cov duab ntawm ya thiab tom qab ntawd ua haujlwm rau IoT ntaus ntawv.

Nws yog txoj hauv kev kom tau txais daim duab kawg. Yog tias koj paub nrog Node.js, koj tuaj yeem ua rau nws nquag dua, piv txwv li pib rub cov duab los ntawm koj cov social media lossis web photo album.

IoT Photo Album

Nws lub hom phiaj sib koom ua ke daim duab tshiab tshaj plaws nrog kev khaws cia hauv zos thiab tso saib nws.

Hauv qhov demo no kuv rov siv IoT ntaus ntawv hauv kuv cov lus qhia yav dhau los. ESP32 tus qauv muaj 4 MB nyem cia, ib puag ncig 3 MB tuaj yeem siv los khaws cov duab. Txog 320x240 JPEG cov ntaub ntawv, nws nyob ib puag ncig 100 - 200 daim. Nws yog qhov zoo txaus hauv feem ntau.

Rau lub zog txuag vim li cas, txhua lub zog ntawm lub ntsuas tsuas yog qhia ob peb daim duab tsis raug thiab tom qab ntawd poob rau hauv kev tsaug zog tsaug zog dua. WiFi kuj tseem raug kaw yog tias tsis tuaj yeem txuas rau nthuav qhia WiFi lossis ua tiav synchronization.

Kauj Ruam 4: Teeb Duab Server

Qhov Code

Kuv tau sau peb caug kab yooj yim HTTP server kom tau raws li qhov xav tau no, koj tuaj yeem pom nws ntawm GitHub:

github.com/moononournation/nodejs-sharp-ht…

yog tias koj tsis paub nrog GitHub, tsuas yog nyem lub pob ntsuab ntawm sab xis sab xis ces xaiv Download ZIP.

Nruab

1. Unzip qhov chaw
2. Rub tawm thiab teeb tsa Node.js, yog tias tseem tsis tau
3. Rub tawm pob cuam tshuam los ntawm cov lus txib hauv qab no:

cd nodejs-ntse-http-server

npm nruab

Khiav

ntawm app.js

Xyuas

1. Muab qee cov duab tso rau hauv daim nplaub tshev yees duab
2. Browser mus rau: https:// localhost: 3200/
3. Koj tuaj yeem pom daim ntawv cais cais cais
4. Browser mus rau: https:// localhost: 3200/ONE_OF_YOUR_PHOTO_FILE_NAME
5. Koj tuaj yeem pom 320x240 hloov pauv thiab txiav cov duab

Kauj Ruam 5: IoT Photo Album

Kho vajtse

Ua raws li kuv cov lus qhia yav dhau los txhawm rau ua IoT ntaus ntawv.

Qhov Code

Rub tawm ESP32 Photo Album qhov chaws ntawm GitHub:

github.com/moononournation/ESP32_Photo_Alb…

Ib zaug ntxiv, yog tias koj tsis paub nrog GitHub, tsuas yog nyem lub pob ntsuab ntawm sab xis sab xis ces xaiv Download ZIP.

ESP-IDF

Yog tias koj tseem tsis tau teeb tsa ESP-IDF, thov saib cov txheej txheem teeb tsa rau cov lus qhia ntxaws kom teeb tsa ESP-IDF:

Windows Teeb Qhia

Mac OS Setup Guide

Linux Teeb Qhia

Kev teeb tsa

Khiav

ua menuconfig

xaiv "serial":

chaw nres nkoj

xaiv "Photo Album Configuration", sau koj tus kheej tus nqi:

• WiFi SSID
• WiFi Password
• Web neeg rau zaub mov
• Web server chaw nres nkoj

Sau

ua txhua yam

Nyem

ua flash

Xyuas

ua saib

Thawj thawj zaug xav tau qee lub sijhawm rau hom SPIFFS thiab rub cov duab. Tom qab ntawd txhua qhov ua rau lub pob nyem yuav qhia 5 daim duab ntawm 5 vib nas this thiab tom qab ntawd nkag mus pw tsaug zog.

Kauj Ruam 6: Flash Card Kev Lag Luam

Kuv xav qhia qee cov tsiaj ntawv flashcard thaum kuv tus menyuam saib daim duab album. Xav tias qhov sib piv yog 4: 1, yog li kuv tuaj yeem tso 5 daim npav npav rau hauv daim nplaub tshev duab rau txhua 20 daim duab. Cov duab thiab flashcards qhia nyob rau hauv random.

Kauj Ruam 7: Zoo Siab Kawm

Nws yog lub sijhawm los muab Daim Duab Duab rau koj cov menyuam. Thaum koj tau rub tawm thawj pawg duab, nws tau npaj nqa nws ib leeg nrog koj cov menyuam!

Kauj Ruam 8: Ib Yam Txog Roj Teeb

Cov cuab yeej IoT no tsim los rau kev txuag roj teeb.

Hauv kuv qhov ntsuas, kev siv lub zog nyob ib puag ncig 0.0 - 0.1 mA thaum pw tsaug zog.

Kuv tab tom ntsuas ntxiv los ntawm suav pes tsawg daim duab tuaj yeem tso tawm rau ib zaug them lub roj teeb.

Koj tuaj yeem ua raws kuv li twitter kom paub cov xov xwm tshiab kawg.
