WebLED for GR-KURUMI

• Web Server & LED Blink

A simple web server that shows and control the value of the LED Digital using an Arduino Wiznet Ethernet shield. This sketch for GR-KURUMI is merged Web-server and LED Blink. You can do controlling and monitoring the RGB LED on GR KURUMI Board via Internet or Local Network.
After opening a web-browser and navigating to the Ethernet shield’s IP address, the GR-KURUMI will respond with just enough HTML for a browser to display the data. A RGB LED on GR-KURUMI is also controlled by the request of web-browser.

• Circuit

• Ethernet shield attached to pins 10, 11, 12, 13


• Pin 22,23,24 has an LED connected on most Arduino boards.


• Pin22: LED_RED


• Pin23: LED_GREEN


• Pin24: LED_BULE

• SW

• Download WIZnet Library - [Wiz_Ethernet_Library]


• Download Ethernet Shield example for GR-KURUMI - [Ethernet Shield examples]




• gr_WebLED.cpp - Web Server & LED Blink

• Code

• Configuration of IP address
  
IPAddress ip(192,168,1,177);





• Initalize the Port (port80 is default for HTTP)
  
EthernetServer server(80);





• Parsing of HTTP GET Message

When web-page address is http://192.168.1.177/G0 to on the Green LEN,
the received HTTP GET Message is as below,

GET /G0 HTTP/1.1
Accept: text/html, application/xhtml+xml,....


So, 5th~7th data are parsed to control RGB LEDs.

//5th~7th data of HTTP GET Message is parsed as parse_arr
parse_arr[0] = '/'
parse_arr[1] = 'G'
parse_arr[2] = '0'


• Contorl RGB LEDs as data pased from HTTP GET Message
  
if(parse_arr[0] == '/'){
switch(parse_arr[1]){
case('R') :
// http://192.168.1.177:R0 => Red LED OFF
if(parse_arr[2] == '0'){
digitalWrite(led_red, HIGH);
// http://192.168.1.177:R1 => Red LED ON
}else if(parse_arr[2] == '1'){
digitalWrite(led_red, LOW);
}
break;
...





• Send a standard http response
  Check current LED status as digitalRead() and Send http respoonse inclued the LED status.
  
int sensorReading = digitalRead(led_red);
client.print("digitalRead(LED_RED)");//client.print(led_red);
client.print(" is ");
client.print(sensorReading);
client.println("
");
...





• Address Lists
  http://192.168.1.177/G0 => Green OFF
  http://192.168.1.177/G1 => Green ON
  http://192.168.1.177/R0 => RED OFF
  http://192.168.1.177/R1 => RED ON
  http://192.168.1.177/B0 => BLUE OFF
  http://192.168.1.177/B1 => BLUE ON
  http://192.168.1.177/B3 => BLINK START
  http://192.168.1.177/B3 => BLINK STOP
