Hi,
i am hoping to use ip calls (http://192.168.1.1:50/?blue ) to make an arduino with an ethernet shield to print the call - so for the call i have written there it would be Serial.println("blue");
i am controlling a motor, led strip(on a relay not transistor), and brightness sensor.
i have been able to find examples for simply off and on but i am having issues adapting the calls for all of these:
"on"
motorOpen
LightSencor - i need to send a response back on the ip port
any ideas?
so

here is the code i have found.
#include <SPI.h>
#include <Ethernet.h>
byte mac[] = { 0xaE, 0xcD, 0xBr, 0xEF, 0xFE, 0xED }; //physical mac address
byte ip[] = { 192, 168, 1, 201 }; // ip in lan
byte gateway[] = { 192, 168, 1, 1 }; // internet access via router
byte subnet[] = { 255, 255, 255, 0 }; //subnet mask
EthernetServer server(80); //server port
String readString;
//////////////////////
void setup(){
pinMode(5, OUTPUT); //pin selected to control
//start Ethernet
Ethernet.begin(mac, ip, gateway, gateway, subnet);
server.begin();
//enable serial data print
Serial.begin(9600);
}
void loop(){
// Create a client connection
EthernetClient client = server.available();
if (client) {
while (client.connected()) {
if (client.available()) {
char c = client.read();
//read char by char HTTP request
if (readString.length() < 100) {
//store characters to string
readString += c;
//Serial.print(c);
}
//if HTTP request has ended
if (c == '\n') {
///////////////
Serial.println(readString); //print to serial monitor for debuging
client.println("HTTP/1.1 200 OK"); //send new page
client.println("Content-Type: text/html");
client.println();
client.println("<HTML>");
client.println("<HEAD>");
client.println("<TITLE>Arduino GET test page</TITLE>");
client.println("</HEAD>");
client.println("<BODY>");
client.println("<H1>Simple Arduino button</H1>");
client.println("<a href=\"/?on\">ON</a>");
client.println("<a href=\"/?off\">OFF</a>");
client.println("</BODY>");
client.println("</HTML>");
delay(1);
//stopping client
client.stop();
///////////////////// control arduino pin
if(readString.indexOf("on") != -1)//checks for on
{
Serial.println(readString.indexOf("on"));
digitalWrite(5, HIGH); // set pin 5 high
Serial.println("Led On");
}
if(readString.indexOf("off") != 1)//checks for off
{
Serial.println(readString.indexOf("off"));
digitalWrite(5, LOW); // set pin 5 low
Serial.println("Led Off");
}
//clearing string for next read
readString="";
}
}
}
}
}
i think the line i am having issues with is this:
i cannot understand how it extracts the call or how to make it send one back for the brightness reading.

good point - thanks.
that does the line
