Hello, I'm trying to open an HTML web server using esp8266-01 with Arduino. But I can't seem to display the IP address and such on the serial monitor display. I have already changed the baud rate to 115200.
I'm using a code that I got from the internet which is this one, and the necessary changes that I did were editing the SSID and Password and that should be about it.
