}
void loop() {
digitalWrite(LED_PIN, HIGH);
delay(500);
digitalWrite(LED_PIN, LOW);
delay(500);
}⚠️ Onboard LED GPIO may vary by board version. Check the actual board pinout if the built-in LED does not respond.
Basic WiFi Test Code
#include <WiFi.h>
const char* ssid = "YOUR_WIFI_NAME";
const char* password = "YOUR_WIFI_PASSWORD";
void setup() {
Serial.begin(115200);
WiFi.begin(ssid, password);
Serial.println("Connecting to WiFi...");
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println();
Serial.println("WiFi Connected!");
Serial.print("IP Address: ");
Serial.println(WiFi.localIP());
}
void loop() {
