hi, i'd like to ask for my error code while compiling

below is my code

#include <ESP8266WiFi.h>

char* ssid = "ESP8266";
char* password = "123123";

void setup()
{
WiFi.begin(ssid,password);
Serial.begin(115200);
while(WiFi.status()!=WL_CONNECTED)
{
Serial.print(".");
delay(500);
}
Serial.printIn("");
Serial.print("IP Address: ");
Serial.print(WiFi.localIP());
}

void loop()
{

}[/b]

and this is error messages

Arduino: 1.8.12 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Disabled (new can abort), All SSL ciphers (most compatible), 4MB (FS:none OTA:~1019KB), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"

C:\Users\AKASACS\Documents\Arduino\Learning_ESP8266_web_server\Learning_ESP8266_web_server.ino: In function 'void setup()':

Learning_ESP8266_web_server:17:10: error: 'class HardwareSerial' has no member named 'printIn'

Serial.printIn("");

^

exit status 1
'class HardwareSerial' has no member named 'printIn'

Should be println() not printIn()

That is a lowercase l, not an uppercase I

ok guest, thanks very much

i think uppercase of i, but this is lowercase of L
