WiFi Client Connectivity with a Google search Added

Community
3

Hi there,
So I went back and created a custom search in the Google API console. It worked very well, returns a Json list of Data, Now I can can build on this by:

  • Parsing the JSON response: If you want to extract specific data like URLs or descriptions from the search results,
  • Handling different queries: I can dynamically change the search query based on input, sensors, or other conditions in the project.

#include <WiFi.h>
#include <HTTPClient.h>

const char *ssid = "GlassSurf-2.4";
const char *password = "SeeedStudio :-p ";


// Google API Key and CSE ID
const String apiKey = "REPLACE with YOUR KEY ";  // Your API key
const String searchEngineId = "REPLACEwithYOURs";  // Your CSE ID

// Search query
const String searchQuery = "Arduino project"; // you can set this to whatever your searching for

void setup() {
  Serial.begin(115200);

  // Connect to Wi-Fi
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi!");
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());

  // Perform Google search
  googleSearch(searchQuery);
}

void googleSearch(String query) {
  if (WiFi.status() == WL_CONNECTED) {
    HTTPClient http;

    // Make sure to replace spaces with '%20' for URL encoding
    String encodedQuery = query;
    encodedQuery.replace(" ", "%20");

    // Correct URL formatting for Google's Custom Search API
    String url = "https://www.googleapis.com/customsearch/v1?key=" + apiKey + "&cx=" + searchEngineId + "&q=" + encodedQuery;
    
    Serial.print("Requesting URL: ");
    Serial.println(url);
    
    // Make GET request to Google Custom Search API
    http.begin(url);
    int httpCode = http.GET();

    // If the GET request was successful
    if (httpCode > 0) {
      String payload = http.getString();
      Serial.println("Search Result:");
      Serial.println(payload);  // Print the raw JSON result from the API
    } else {
      Serial.print("Error on HTTP request: ");
      Serial.println(httpCode);
    }

    http.end();  // Free resources
  } else {
    Serial.println("WiFi not connected");
  }
}

void loop() {
  // Nothing to
}

The output is Long so I’ll only add some of it.

Connecting to WiFi...

Works GREAT!
