webserver_uno.ino:6:65: fatal error: uartWIFIUNO.h: No such file or directory

Error compiling.
hello sir i am getting this error
i am using same code as you given above
My IDE is ARDUINO 1.6.5
Hi! Yogi,
Download the Code Library named
uartWIFIUNO.h <----- and placed it into your Arduino Library located at My Documents/ Arduino / Libraries just copy the whole directory and phase. Let me know if you still having an error compiling the code above.
Hi Yogi,
I guess there some issue with the library it think it is absolute….
#include “ESP8266.h >
Use this library > https://github.com/itead/ITEADLIB_Arduino_WeeESP8266
1. Make it sure, you have complete library as required for the sketch code,
You don’t need to download this library.
#include “ESP8266.h > Download it Here “Use this library > https://github.com/itead/ITEADLIB_Arduino_WeeESP8266”
2. Make it sure you place a 200uf capacitor between GND and VCC to stabilize the logic voltage going to ESP8266.
3. Try fist using USB Serial Communication by placing the pin to ESP TX and RX to pin 0,& 1, Test the communication between the ESP8266 to Arduino by using AT Command.

hello, my code’re error when checking

how can I fix

where is uartWIFIUNO.h sir….? I cannot find it in your page and code library on your post…
please help me to solve the error

sir i succes to added library to Arduino IDE, and succes to compile and upload sketch to arduino UNO. But i find in serial monitor, that ”
AT+RST
Module have no response
Begin error
Init error
please tell me about this error..
my email : rahmatfauren28@gmail.com
There are two possible error in your case first is your serial communication is busy, second is if your using Arduino or the code below try to shift your serial communication RX = 0; & TX = 1; add 100uf capacitor to GND and VCC to your ESP8266 module, then use coolterm serial tool to verify that your ESP8266 module is connected in a proper way.
Regards
Hi,
i like your instruction and got it to work…
I have some issues with the schematics. It would be great when the pinout of the esp8266-01 would be like its on the pc board.
Sorry for the bad english but i hope you know what i mean.
how to know the ip address of esp8266 wifi module
Serial or software serial, open your serial monitor then connect to the port.
you can used Arduino Serial Monitor, Putty, TermCool any Serial tools or Use LCD to print the IP Address of ESP82XX | lcd.println(IP Address: ); lcd.print(ipstring);
———————————————————
String ipstring = wifi.showIP();
DebugSerial.println(ipstring);
——————————————————–
sir one doubt the library pasting is in rar format or in extract file format
?????? you need to extract the file which is in the rar file then then upload the code using your IDE. don’t forget the code libraries to place in your code library directory. :)
Hi sir,
“Wiring ESP8266 WiFi Transceiver on Arduino with Relay” program run but actually,
when can i firmware in esp8266-01?
when can i use “at cammad “?
i am reading but no any idea firmware and at cammand.
please explain me.
I am getting this error

Try to change the library use ESP8266WiFi

Did we need to replace back the atmega328 after the set up of at-command??
