Code Example - Joy-it ESP-01S Quick Start Manual

3. CODE EXAMPLE

Now you can simply copy the following code example into your Arduino
IDE and upload it to your ESP-01S.
#include <ESP8266WiFi.h>
const char* ssid = "MeineWlanSSID";
WiFi SSID here
const char* password = "MeinWlanPasswort";

digitalWrite(RELAY, LOW);
// Connect to the WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to

WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED){
