问题的解决方法：通过使用FirebaseArduino库将Firebase的API密钥添加到Arduino IDE中，并确保将WiFi模块正确连接到Arduino板子上。

示例代码：

#include #include

#define WIFI_SSID your_SSID" #define WIFI_PASSWORD "your_PASSWORD"

#define FIREBASE_HOST "your_project_name.firebaseio.com" #define FIREBASE_AUTH "your_API_KEY"

void setup() { Serial.begin(9600);

WiFi.begin(WIFI_SSID, WIFI_PASSWORD); Serial.print("Connecting to Wi-Fi"); while (WiFi.status() != WL_CONNECTED) { Serial.print("."); delay(1000); } Serial.println(); Serial.print("Connected with IP: "); Serial.println(WiFi.localIP());

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH); }

void loop() { // do something }'
