Nws yog kuv Qhov Kev Kawm Caij Ntuj Sov. Kuv xav tsis thoob thaum kuv hnov peb tuaj yeem taug qab qhov chaw ib qho khoom siv yam tsis siv GPS module tsuas yog siv NodeMCU. Los ntawm qhov no peb tuaj yeem taug qab txhua lub cuab yeej. Koj kuj xav tsis thoob li cas peb tuaj yeem taug qab cov cuab yeej siv tsuas yog WiFi. Nov yog cov lus piav qhia kom nkag siab nws.

• · Nws yog Scan koj yuav luag txhua WiFi.
• · Xa cov cuab yeej no mus rau Google siv Google API
• · Raws li qhov no Nws yog nrhiav koj lub cuab yeej qhov chaw
• · Koj muaj kev sib txuas network zoo rau Txoj Haujlwm no.

Kauj Ruam 1: Qhov Chaw & Cuab Yeej

Qhov

• NodeMCU (ESP8266 1.0 12E)
• USB Cable

Cov cuab yeej

Arduino IDE nrog NodeMcu 1.0 12E Board

Google API

Kauj ruam 2: Nrhiav Google API

• Qhib Koj Tus browser thiab ntaus: console.developer.google.com
• Tsim txoj haujlwm tshiab
• Tom qab Tsim Txoj Haujlwm Tshiab nyem rau ntawm daim ntawv pov thawj
• Nyem rau API Key

• Koj tus lej API tau tsim

  Txhawm rau nkag siab yooj yim pom cov duab hauv qab no |>

Kauj Ruam 3: Teeb NodeMCu ntawm Arduino IDE

• Rub tawm Arduino IDE los ntawm qhov txuas hauv qab no:- https:// www. Lub ntsiab/Software arduino.cc/en/
• Ntxiv Node MCu board ntawm Arduino IDE

• Rau kev xa cov cai ntawm NodeMCU koj yuav tsum ntxiv NodeMCu pawg thawj coj ntawm ARDUINO IDE.

  • Mus rau cov ntawv & Nyiam nyob hauv Arduino IDE
  • Thiab hauv Pawg Tswj Xyuas Kev Tswj Xyuas Ntxiv tau theej cov kab ntawv txuas hauv qab no

  • arduino.esp8266.com/stable/package_esp8266c…

  • thiab nyem Ok
  • Pawg thawj coj tau rub tawm
  • Mus rau cov cuab yeej thiab pawg thawj coj saib thiab xaiv NodeMCU 1.0 12E
  • Saib daim duab avobe kom nkag siab yooj yim

Kauj Ruam 4: Rub ArduinoJson Library

• Mus rau qhov

Sketch Xws li Lub Tsev Qiv Tswj Lub Tsev Qiv Ntawv

Ntaus Arduino Json hauv lub thawv tshawb nrhiav

Rub tawm qhov hloov tshiab kawg ntawm ArduinoJson lub tsev qiv ntawv

tom qab rub tawm lub tsev qiv ntawv nyem ze

Ntxiv tsev qiv ntawv los ntawm

SketchincludeLibraryArduinoJson

Kauj Ruam 5: Txoj Haujlwm

Tshaj tawm cov haujlwm hauv qab no ntawm NodeMCU pawg thawj coj. thiab pom koj lub cuab yeej (NodeMCU 1.0 12E board) qhov chaw ntawm Serial monitor.
