Code Refactoring

To avoid repeating Wi-Fi connection code, we can abstract the connection process into a separate function and save it in a separate file. On the right side of the current tab view, click the **…** and select **New Tab**. Name the new file “WiFiHelper.ino”. ![[Pasted image 20250125225958.png]] Move all the Wi-Fi related code into the “WiFiHelper.ino” file. ```cpp #include const char* ssid = "your_SSID"; const char* password = "your_PASSWORD"; void connectToWiFi() { Serial.println("Connecting to Wi-Fi..."); WiFi.begin(ssid, password); // Wait for connection while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting..."); } Serial.println("Wi-Fi connected!"); Serial.print("Local IP: "); Serial.println(WiFi.localIP()); } ``` In the original file, the code can be simplified like this: ```cpp void setup() { Serial.begin(115200); connectToWiFi(); } void loop() { } ``` Save the Arduino code if you haven’t already. When saving, Arduino will automatically create a folder and an .ino file using the name you specify. In that folder, you will find the WiFiHelper.ino file. If you need to access Wi-Fi functionality in other Arduino sketches, simply copy this file into the corresponding folder and use the connectToWiFi() function. ![[Pasted image 20250125230922.png]]
