Pin Connection
ARDUINO UNO ESP8266
RX --------------> TX
TX --------------> RX
VCC--------------> 3.3
CH_PD ----------> 3.3
GND -------------> GND

Try it with another carriage return and line feed:

GET /arduino/?light=on HTTP/1.0\r\n\r\n

The first one indicates the end of the one line you send.
The second one (an empty line) indicates the end of all your headers, i.e. the end of your request.

after putting this line on textbox then i press Enter button or Send Button nothing will happen

That often happens when you confuse the device by trying to use the serial port to communicate with it AND with the PC. Get the device off of the hardware serial port.
