hello ,
I'm a beginner to arduino, I want to do a project that will let show to the web by using that this button and it's state been pressed , now what I'm trying to do is to connect with one device , and I'm having this problem in coding , the code will execute like the following :
GET /192.168.0.66 HTTP/1.1
The state is LOW
GET /192.168.0.66 HTTP/1.1
The state is LOW
GET /192.168.0.66 HTTP/1.1
The state is LOW
....
until the end , I have two question , first does this code affect the arduino because the browser is repeating the same message to the same port , second about the code I have tried to do some changes but it gives me an error or the browser does not show any message , so what is my specific real problem .
/* The user should open the browser and enter the specific IP
here I will use a button in the circuit , this button will show
the state of the circuit , the normal action is LOW , then the
browser will show a message " the state is LOW "
when the button is been pressed the browser will show the message
"The state is HIGH"*/
