2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Txhawm rau pib nrog txoj haujlwm no, Koj xav tau cov hauv qab no:

• esp8266 (NodeMcu v3 Lua)
• google tus account (firebase)

Koj tuaj yeem yuav tau esp8266 los ntawm no:

• amazon.com
• aliexpress.com

Kauj Ruam 1: Teeb Arduino IDE, Nruab Esp8266 Pawg Thawj Coj:

Nruab esp8266 Board:

Qhib Arduino IDE> Cov Ntaub Ntawv> Nyiam> ntxiv Tus Thawj Saib Xyuas Haujlwm URLs> "https://arduino.esp8266.com/stable/package_esp8266c …> OK

Cuab Yeej> Pawg Thawj Coj:> Tus Thawj Saib Xyuas Pawg> esp8266> nruab

Kauj Ruam 2: Teeb Arduino IDE, Nruab Arduino Json Library:

Nruab Arduino json tsev qiv ntawv:

Nruab version 5.13.1

Saib install video NTAWM NO

Kauj Ruam 3: Teeb Arduino IDE, Nruab Firebase Library:

Nruab Firebase tsev qiv ntawv:

Rub tawm qhov tseeb ruaj khov NTAWM NO> unzip hauv "Documents / Arduino / libraries"

NCO TSEG, Muaj kab nyob hauv "v0.3 Bi-directional streaming support"> hloov cov ntiv tes NYEM QHOV NO INFO

Kauj Ruam 4: Firebase, Tsim Txoj Haujlwm:

Tsim Firebase Project:

Mus rau "https://console.firebase.google.com"

Kauj Ruam 5: Firebase, Txoj Cai Txoj Haujlwm:

Txoj cai txoj haujlwm:

Database (Realtime Database)> cov cai

{/* Mus ntsib https://firebase.google.com/docs/database/security kom paub ntau ntxiv txog cov cai kev nyab xeeb. */ "cov cai": {".read": tseeb, ".write": tseeb}}

Kauj Ruam 6: Firebase, Cov Ntaub Ntawv Teev Npe Sijhawm:

Realtime Database cov ntaub ntawv:

Database (Realtime Database)> Cov Ntaub Ntawv

Ntxiv: "LED1"> "0"

Kauj ruam 7: Code:

#suav nrog

#suav nrog

#define WIFI_SSID "SSID" #define WIFI_PASSWORD "WIFI PASSWORD" #define FIREBASE_HOST "?????????????? firebaseio.com" #define FIREBASE_AUTH "AUTH KEY"

int LED1 = 4;

void teeb tsa ()

{Serial.begin (115200);

tus pinMode (LED1, OUTPUT);

ncua (2000);

Serial.println ('\ n'); wifiConnect ();

Firebase.begin (FIREBASE_HOST, FIREBASE_AUTH);

ncua (10);

}

void lub voj ()

{Serial.print (Firebase.getString ("LED1") + "\ n");

analogWrite (LED1, Firebase.getString ("LED1"). toInt ());

ncua (10);

yog (WiFi.status ()! = WL_CONNECTED)

{wifiConnect (); } ncua (10);

}

tsis muaj wifiConnect ()

{WiFi.begin (WIFI_SSID, WIFI_PASSWORD); // Txuas mus rau lub network Serial.print ("Txuas rau"); Serial.print (WIFI_SSID); Serial.println (“…”);

int tus qhia = 0;

thaum (WiFi.status ()! = WL_CONNECTED) {// Tos kom Wi-nkaus txuas txuas qeeb (1000); Serial.print (++ tus qhia); Serial.print (''); }

Serial.println ('\ n');

Serial.println ("Kev sib txuas tau tsim!"); Serial.print ("IP chaw nyob: / t"); Serial.println (WiFi.localIP ()); // Xa tus IP chaw nyob ntawm ESP8266 mus rau lub khoos phis tawj}

Kauj Ruam 8: Txoj Cai, Cov Ntaub Ntawv Tus Kheej:

cov ntaub ntawv tus kheej:

SSID> lub npe ntawm koj lub network wifi

WIFI PASSWORD> password ntawm koj lub network wifi

FIREBASE HOST> qee yam xws li "?????????????. Firebaseio.com". Koj tuaj yeem pom nws hauv "Cov Ntaub Ntawv" tab ntawm koj Lub Sijhawm Teev Npe.

AUTH KEY> Txoj haujlwm teeb tsa> Cov nyiaj pabcuam> Cov ntaub ntawv zais cia

Kauj Ruam 9: Esp8266 Tsav Tsheb:

Rub tawm:

Nyem qhov no> unzip thiab nruab

Kauj Ruam 10: Xeem Txoj Cai:

Upload chaws:

siv tus qauv esp8266 hauv tus thawj tswj hwm pawg> nyem "ESP-12E module".

Qhib serial saib thiab teeb nws rau "115200".

Thiab koj yuav tsum tau txais cov ntaub ntawv zoo ib yam li hauv koj lub database.
