hi
i am using WiFi Web Server example
the problem i am having is
client.print("<body bgcolor="#00FF00">");
gives this error
wifiServer:87: error: stray '#' in program
wifiServer.ino:87:41: error: invalid suffix "FF00" on integer constant
wifiServer.ino: In function 'void loop()':
wifiServer:87: error: expected `)' before numeric constant
so i am trying to change background color of the web page
shouldn't this work?
is there another way?
i am using a arduino 2560 and the wifi shield
i am trying to set up a web page that monitors
water level and temp of my grow room
thanks

hi guys
i have a similar question
how do you limit the amount of digits to the right of the decimal point
temp_f = sht1x.readTemperatureF();
lcd.print("Temperature: ");
lcd.print(temp_f, DEC);
prints way to many digits i just want to print 2 digits to the right of decimal point
thanks

hi
"You have several issues. First, user downloaded libraries do NOT go in the core library folder. Doing that causes all kinds of issues.
The pde extension is for pre-1.0 versions of the IDE. You appear to be using one with post-1.0. Why?"
ok i read that was where i should put them and i was trying with both 1.03 and 0023
and have same problems
so where should LiquidCrystall_I2C go?
should i redownload arduino 1.03 and start over?
thanks

hi
i have a uno v1 with a sensor sheild v4 connected to a ywrobot I2C lcd 16,2
and can't get this simple program to display
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x38); // Set the LCD I2C address
#define BACKLIGHT_PIN 13
void setup()
{
// Switch on the backlight
pinMode ( BACKLIGHT_PIN, OUTPUT );
digitalWrite ( BACKLIGHT_PIN, HIGH );
lcd.begin(16,2); // initialize the lcd
lcd.home (); // go home
lcd.print("Hello, ARDUINO ");
lcd.setCursor ( 0, 1 ); // go to the next line
lcd.print (" WORLD! ");
}
void loop()
{
}
can anybody see what i am doing wrong?
i also tried a sainsmart 20,4 lcd with no results
