Arduino Ethernet

good Afternoon

This code is my graduation project in which I blow a fan and this indicator crosses an optical sensor, the thing that well to that. The thing is that you connect to an ethernet shield, the communicating me but there is a line of code that is not where to locate it is to:

if (digitalRead (2) == LOW)
{
conta ++;
Serial.println (conta);
client.println (conta);
delay (1000);
}

I show the code, because where ubice not work and the first result is maintained.

  Web Server
 
 A simple web server that shows the value of the analog input pins.
 using an Arduino Wiznet Ethernet shield. 
 
 Circuit:
 * Ethernet shield attached to pins 10, 11, 12, 13
 * Analog inputs attached to pins A0 through A5 (optional)

Does that look like intelligent indenting or does that look like crap to you? It looks like crap to me.

Your translator needs new batteries.
