Kauj ruam 1: Vim li cas?
WiFi Analyzer muaj txiaj ntsig zoo hauv qee qhov xwm txheej:
- WiFi txhua qhov chaw tam sim no thiab 2.4 GHz tseem yog qhov sib xws tshaj plaws. Ntawm kuv lub tsev thiab chaw ua haujlwm, Kuv tuaj yeem pom ntau dua 20 AP SSID tab sis 2.4 GHz tsuas muaj 11 txoj hauv kev. Qhov ntawd txhais tau tias lub teeb liab cuam tshuam ntau heev thiab cuam tshuam kev ua haujlwm tsis zoo ntawm lub network. Xaiv txoj cai raug rau koj li AP tseem ceeb heev. Piv txwv li, hauv qhov xwm txheej yees duab saum toj no, channel 8 thiab 9 zoo dua li lwm qhov.
- Yog tias koj xav tau siv WiFi dawb hauv txoj kev, koj tuaj yeem xaiv ib qho uas muaj lub teeb liab muaj zog tshaj plaws, tab sis nws tsis tas li yog lub network nrawm tshaj plaws. yog tias koj tuaj yeem pom cov channel uas muaj kev sib tshooj tsawg dua koj yuav tsum muaj kev paub zoo dua. Piv txwv li, hauv qhov xwm txheej yees duab saum toj no, channel 4 thiab 6 zoo dua li channel 11.
- Cov cuab yeej siv tau sib qhia cov ntaub ntawv wirelessly los ntawm kev tsim AP ib ntus nrog cov channel tsis raug. Qee lub sij hawm nws tuaj yeem tsoo lub channel uas twb tibneeg hu tauj coob thiab xa cov ntaub ntawv qeeb heev. WiFi Analyzer tuaj yeem pab koj txheeb xyuas qhov xwm txheej no, ib txwm rov pib dua lub cuab yeej sib koom ua haujlwm sib txuas tuaj yeem hloov mus rau lwm qhov channel tsis raug.
- Yog tias koj pom lwm qhov xwm txheej muaj txiaj ntsig, tawm lus rau kuv.;>
Kauj ruam 2: Kev npaj
Cov ntaub ntawv pob tshab
Tic Tac yog ib qho yooj yim nkag tau yooj yim pob tshab qab zib. Tab sis ceev faj nws muaj ntau qhov loj, tshwj xeeb tshaj yog koj yuav nws hauv ntau lub caij sib txawv thiab lub tebchaws. Qee qhov tuaj yeem haum 2.2 nti LCD thiab qee qhov loj dua tuaj yeem haum 2.4 nti LCD nrog cov pawg tawm.
Zaub Zaub
Ib qho ili9341 LCD uas tuaj yeem haum rau hauv lub thawv qab zib yuav tsum ua li cas, Kuv siv TM022HDH26 lub sijhawm no.
Roj teeb
Ib lub roj teeb LiPo me me me me uas lub LCD yuav tsum yog. Hauv kuv qhov kev ntsuas, qhov Circuit Court no qee zaum yuav kos ntau dua 200 mA. Txhawm rau ua kom lub Circuit Court tsis kos ntau dua 1C tam sim no los ntawm lub roj teeb, nws raug nquahu kom xaiv lub roj teeb ntau dua 200 mAh.
Pawg Thawj Coj
Txhua lub micro USB LiPo them lub rooj tsavxwm uas tuaj yeem siv tau nrog koj lub roj teeb.
Pawg ESP
Ib qho ESP8266 lub rooj tsavxwm nrog SPI tus pin tawm yuav tsum yog, kuv siv ESP-12 lub sijhawm no.
3V3 tus tswj hwm
Kuv siv HT7333-A. (AMS1117 tsis pom zoo, nws thim lub zog ntau dhau thaum tos)
PNP transistor cov
Ib qho qub PNP transistor, Kuv muaj qee tus SS8550 hauv tes.
Lwm tus
3 x 10k resistors, 470 uf capacitor, 100 nf capacitor, khawm rau rov pib dua ESP pawg thawj coj, qee qhov xaim rau txuas thiab lub nplhaib tseem ceeb rau dai qhov no ntawm koj lub hnab.
Kauj Ruam 3: Txoj Haujlwm ESP8266
Nws tau pom zoo qhov kev pab cuam ESP8266 ua ntej siv nws nrog lwm yam khoom siv.
Rub tawm qhov chaws ntawm no:
github.com/moononournation/ESP8266WiFiAnal…
Sau thiab ua haujlwm ESP8266 nrog Arduino software.
Koj tuaj yeem pom cov ntsiab lus ntxiv hauv kuv cov lus qhia yav dhau los:
www.instructables.com/id/ESP8266-Bread-Boa…
Kauj Ruam 4: Lub Thawv Qab Qab Qab
- Thaj lub thawv kom haum rau hauv LCD
- laum ob lub qhov rau dai lub nplhaib tseem ceeb
Kauj Ruam 5: Kev txhawj xeeb txog roj teeb
Hauv kuv cov lus qhia yav dhau los, Kuv tau ntsuas lub zog siv hluav taws xob hauv cov laug cam sib txawv thiab cov roj teeb sib txuas. ESP-12 nrog HT7333-A tuaj yeem ua lub zog txuag hluav taws xob zoo. Kuv tuaj yeem hla lub zog hloov pauv rau kev tsim qauv yooj yim, tus kws tshuaj ntsuam xyuas tsib zaug thiab poob rau hauv hom pw tsaug zog. Tsuas yog nyem qhov pib dua tuaj yeem qhib nws dua. Xav tias scan 1 zaug siv 1.1 mAh, txhua txhua hnub scan 5 zaug thiab tsaug zog 1 teev haus 0.31 mAh, 400 mAh tuaj yeem nyob ib hlis:
400 mAh / (5 x 1.1 mAh + 24 x 0.31 mAh) ~ = 31 hnub
Kauj Ruam 6: Kev Ua Haujlwm Soldering
Ob zaug txheeb xyuas koj cov ntaub ntawv LCD rau tus lej txhais.
Nov yog cov ntsiab lus sib txuas:
them nqi B + -> LiPo + ve
them nqi pawg B- -> LiPo -ve them lub rooj tawm+ -> 3V3 tus tswj hwm lub zog tawm tswv yim them tawm lub rooj tawm - -> 3V3 tus tswj GND, ESP GND, LCD GND, capacitors 3V3 tus tswj lub zog tso tawm -> ESP Vcc, PNP transistor Emitter, capacitors PNP transistor Base -> 10 k resistor -> ESP GPIO 4 PNP transistor Collector -> LCD Vcc, LCD LED LCD SCK -> ESP GPIO 14 LCD MISO -> ESP GPIO 12 LCD MOSI -> ESP GPIO 13 LCD D/C -> ESP GPIO 5 LCD CS -> ESP GPIO 15 ESP EN -> 10 k resistor -> ESP Vcc ESP GPIO 15 -> 10 k resistor -> ESP GND ESP RST -> pib dua khawm -> ESP GND

Kauj Ruam 8: Txuas lub Nplhaib Ntsiab
Kauj Ruam 9: Zoo Siab Kuaj
Nws yog lub sijhawm los qhia tawm koj txoj haujlwm nrog phooj ywg!
Kauj Ruam 10: Kev Ntsuam Xyuas Kev Nyuaj Siab
Tus menyuam ntxim nyiam heev hauv qhov khoom no, yog li kuv tau caw nws pab los ntsuas qhov kev nyuaj siab.
Nws yuav ua haujlwm random:
- nyem lub npov thiab qhib lub sijhawm scanning
- co tes
- poob xeem
- kauj ruam xeem
- kev ntsuam xyuas dej tsis haum
Tom qab ob peb lub asthiv xeem, Kuv tau sau cov ntawv xeem:
- Lub roj teeb 500 mAh tuaj yeem ua haujlwm dhau 3 lub lis piam
- Kuv txoj haujlwm ua haujlwm soldering tuaj yeem tiv thaiv tus menyuam co thiab ua rau poob siab
- Lub thawv Tic Tac tuaj yeem tiv taus 70 cm qhov siab poob thiab 10 kg kauj ruam ntawm kev thauj khoom
- Lub thawv kuj tuaj yeem tiv taus dej me me
Kuv yuav hloov kho lub roj teeb tiag tiag tom qab ntawm;>
