Hi guys,

I'm not a good programmer. I'm a beginner only.

I have 1 question. I made a code :
Code: [Select]
int cap1 = 2;
int cap2 = 3;
int cap3 = 4;
int cap4 = 5;
int cod1 = 9;
int cod2 = 10;
int cod3 = 11;
int cod4 = 12;
int cod5 = 13;


void setup (){
  pinMode(cap1, INPUT_PULLUP);
  pinMode(cap2, INPUT_PULLUP);
  pinMode(cap3, INPUT_PULLUP);
  pinMode(cap4, INPUT_PULLUP);
  pinMode(cod1, OUTPUT);
  pinMode(cod2, OUTPUT);
  pinMode(cod3, OUTPUT);
  pinMode(cod4, OUTPUT);
  pinMode(cod5, OUTPUT);

  Serial.begin(9600);
}
void loop (){

 
fonction1();
delay(2000);
digitalWrite(cod1, LOW);
digitalWrite(cod2, LOW);
digitalWrite(cod3, LOW);
digitalWrite(cod4, LOW);
digitalWrite(cod5, LOW);


fonction2();
delay(2000);
digitalWrite(cod1, LOW);
digitalWrite(cod2, LOW);
digitalWrite(cod3, LOW);
digitalWrite(cod4, LOW);
digitalWrite(cod5, LOW);


fonction3();
delay(2000);
digitalWrite(cod1, LOW);
digitalWrite(cod2, LOW);
digitalWrite(cod3, LOW);
digitalWrite(cod4, LOW);
digitalWrite(cod5, LOW);


   
}
 
 
void fonction1 (){
 
  int capteur1 = digitalRead(cap1);
 
  digitalWrite(cod2, HIGH);
  digitalWrite(cod4, HIGH);
 
 
if (capteur1 == HIGH){
  Serial.println("S1 = 50%");
  }
  else{
  Serial.println("S1 = 100%");
  }
  delay(1);
 
}


void fonction2 (){
 
  int capteur2 = digitalRead(cap2);
 
  digitalWrite(cod1, HIGH);
  digitalWrite(cod3, HIGH);

 
 
  if (capteur2 == HIGH){
  Serial.println("S2 = 50%");
  }
  else{
  Serial.println("S2 = 100%");
  }
  delay(1);
 
 
}



void fonction3 (){
 
  int capteur3 = digitalRead(cap4);
 
  digitalWrite(cod1, HIGH);
  digitalWrite(cod5, HIGH);

 
 
  if (capteur3 == HIGH){
  Serial.println("S3 = 50%");
  }
  else{
  Serial.println("S3 = 100%");
  }
  delay(1);
 
 
}


And I want that Serial.println switch to client.println. Wich is viewable by a webpage.


I have this part of a code that I found. This is I think the basic lines of a webserver html page.

Code: [Select]
#include <SPI.h>
#include <Ethernet.h>

// MAC address from Ethernet shield sticker under board
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 1, 20); // IP address, may need to change depending on network
EthernetServer server(80);  // create a server at port 80



void setup()
{





    Ethernet.begin(mac, ip);  // initialize Ethernet device
    server.begin();           // start to listen for clients
}




void loop ()
{
 


{
    EthernetClient client = server.available();  // try to get client

    if (client) {  // got client?
        boolean currentLineIsBlank = true;
        while (client.connected()) {
            if (client.available()) {   // client data available to read
                char c = client.read(); // read 1 byte (character) from client
                // last line of client request is blank and ends with \n
                // respond to client only after last line received
                if (c == '\n' && currentLineIsBlank) {
                    // send a standard http response header
                    client.println("HTTP/1.1 200 OK");
                    client.println("Content-Type: text/html");
                    client.println("Connection: close");
                    client.println("Refresh: 2");
                    client.println();
                    // envoyerla page web en ''PRINT''
                    client.println("<!DOCTYPE html>");
                    client.println("<html>");
                    client.println("<head>");
                    client.println("<title>Serveur 1.0</title>");
                    client.println("</head>");
                    client.println("<body>");
                    client.println("<h1><center>Serveur V1.0</center></h1>");
                   
// maybe the client.println here ??

                    client.println("</body>");
                    client.println("</html>");
                    break;
                }
                // every line of text received from the client ends with \r\n
                if (c == '\n') {
                    // last character on line of received text
                    // starting new line with next character read
                    currentLineIsBlank = true;
                }
                else if (c != '\r') {
                    // a text character was received from client
                    currentLineIsBlank = false;
                }
            } // end if (client.available())
        } // end while (client.connected())
        delay(1);      // give the web browser time to receive the data
        client.stop(); // close the connection
    } // end if (client)
}
}


Could I merge them togheter???



thank you everybody.

Not sure just what you are trying to do, but below is some combined client/server code.

//web page buttons make pin 5 high/low
//use the ' in html instead of " to prevent having to escape the "
//address will look like http://192.168.1.102:84 when submited

HI,

I'm working on an arduino project. I'm looking for write on a webpage the state of 3 function.


For exemple, when the output2 and the output3 are on, tell me if the input1 or input2 or input3 is ON. then write on the webpage the value.


It's hard for me to explain that. But I want to print what i see in the monitor on a web page. I already made it with a simplest sketch. But I don't know why that not work with the new sketch I shown you.

The only different thing is the 3 chunk of ''void fonction1()'' 'void fonction2()'' 'void fonction3()''

Test that with your arduino, you will probably undestand !!!


Code: [Select]

// Take a wire, ground the input pin ''cap1 to cap4'' Take a look on ''fonction1() to fonction3() you will see that

Aren't arrays wonderful. So much less code needed.

Code: [Select]
fonction1();
Have you looked at the reference page? Did you see any functions with stupid names like these? The function does something. The name should reflect that.

int cap[] = {2, 3, 4, 5};
int cod[] = {9, 10, 11, 12, 13};


Looks better?




not sure what you are trying to sy with the function.



fonction1() was just a name called from the void loop()...
What is your point?

My point is that names that don't mean anything usually indicate that you don't understand the code. If you don't understand the code, you'll have a hard time merging the two bits of code.

did you take a look on the complet code?

The code is working, Did you test it?


fonction1 was called from the void loop().

I can rename it for you if you don't love the french word;)





As i said, i'm not a expert, I'm a beginner.

Dec 14, 2013, 02:27 pm
this is an exemple taht I saw from the reference pages. I think is the same thing I made in my sketch.



void loop() {

  while (digitalRead(buttonPin) == HIGH) {
    calibrate();
  }


void calibrate() {
}




Maybe I'm wrong...

The difference is simply that calibrate tells you something about what the function does. It's not ideal, I'd prefer that the name tells you what it's calibrating, but at least it's a clue. Fonction1 on the other hand tells you nothing. Worse, it implies that you're going to have Fonction2 and Fonction3 later on. You may be able to keep what they're for in your head, but why bother when you can simply give each function a sensible name that gives you that information.

Dec 15, 2013, 02:33 pm
okay I'll keep in mind. So I will change the name for something more significant.


So, What should I do to change the Serial.println to client.print.

If there is no other function after the void loop it works.

Use a text editor.

If there is no other function after the void loop it works.

void is a return type. If is NOT part of the function name. Stop using "void loop". Use "loop".

You need to explain this statement. Putting more functions after loop() does not affect the behavior of loop(), unless the extra functions cause memory problems, like using all of it and then some.
