Hi Everyone !
I wish to display a lcd bargraph for liquid level. The code does not compile gives an error 'Void' does not name type.
This is the first problem I am facing, I know there are lot more waiting.....
Kindly help me =(

Void display() {

It's "void" not "Void".

Also check your parentheses, if you do an "auto format" it says "Too many left parentheses".

Also this isn't valid C:

LiquidCrystal lcd(12,11,6,7,8,9) when LCD is used

There should be a semicolon after the brackets, and are you missing a comment there?

Thanks Mr. Nick
The sketch is compiled with your valuable instructions.
When buttonpin1 is activated it displays the black character and MIN in the lcd. it is OK
but No further displays when the other button pins are activated.
I wish to display
2 black charactors and 25% when buttonpin2 is activated
3 black charactors and 50% when buttonpin3 is activated
4 black charactors and 75% when buttonpin3 is activated
5 black charactors and Max% when buttonpin5 is activated

What could be the problem?

Can you post the revised sketch please?

Doesn't doing a write advance the cursor? Can't this just be:

    lcd.write(1); // write to screen the custom graph character.
    lcd.write(0); // write to screen the custom clear character.
    lcd.write(0); // write to screen the custom clear character.
    lcd.write(0); // write to screen the custom clear character.
    lcd.write(0); // write to screen the custom clear character.
    lcd.setCursor(6, 0); // set cursor position.
    lcd.print("MIN");// write text next to graph

Or even:

    lcd.setCursor(0, 0); // set cursor position.
    lcd.write(1); 
    for (byte i = 0; i < 4; i++)
      lcd.write(0); 
    lcd.setCursor(6, 0); // set cursor position.
    lcd.print("MIN");// write text next to graph

Ditto for the other cases.

case3:

That is not the same as:

case 3:

Ditto for case4, and case5.

    if (digitalRead(buttonpin3) == LOW) //50%

Do you have pull-up resistors on all these pins?

  if (digitalRead(buttonpin2) == LOW) // 25%

{
   state2 = !state2;  // toggle state
   if (state2 >0 ){
     Level = 2;
     if (state2 ==0 ){
       Level =1;
     }
     delay(500);  // debounce
   }
   if (digitalRead(buttonpin3) == LOW) //50%

{
  ...
   }
   if (digitalRead(buttonpin4) == LOW) // 75%
   {
    ...
   }
   if (digitalRead(buttonpin5) == LOW) { // max
   ...
   }
   if (digitalRead(buttonpin5) == HIGH) {  // max reed off
    ...
   }
   EEPROM.write(0, Level); // Write to eeprom memory position 0 the Level value.

// delay(100); // small delay at each loop.
 }

You just threw in a squiggly bracket to make the compiler error go away didn't you? It's in the wrong place. All those other ifs are under the first if. So if buttonpin2 is not pressed it doesn't test them.

    EEPROM.write(0, Level); // Write to eeprom memory position 0 the Level value.

You should read some of the recent threads about EEPROM writing. The EEPROM has a life of about 100,000 writes. You will wear it out in a couple of seconds. Try only writing to it if the level changes, or perhaps only every minute or so (or both).

I have corrected the "case" problem

Do you have pull-up resistors on all these pins?

10K pull up resistors are connected to all these pins

You will wear it out in a couple of seconds. Try only writing to it if the level changes, or perhaps only every minute or so (or both).

I have done a blunder. Can you help me to write the EEPROM writes for this sketch ?

Hello there !

This code displays the levels 25%,50%,Min,75% without activating the buttonpins with time delay and Level Max is missing.It does not display coressponding to the states of the button pins. There is no effect in the displays even the buttonpins are switched ON or OFF.

I am writing to the EEPROM the state of the levels. Is it because of EEPROM write or something else ??
Please help !!

You ignored what I said here:

You should read some of the recent threads about EEPROM writing. The EEPROM has a life of about 100,000 writes. You will wear it out in a couple of seconds.

Why bother doing this:

 if (digitalRead(buttonpin2) == LOW) // 25%
  {
    state2 = !state2;  // toggle state
    if (state2 >0 ){ 
      Level = 2;
    }
    if (state2 ==0 ){ 
      Level =1;
    }
    delay(500);  // debounce
  }
...
  }
  Level=state1+state2+state3+state4+state5;

You make Level to be 1 or 2, and then just overwrite it with adding the states together.

The states are going to be 0 or 1, right? So why add them?

  Level=state1+state2+state3+state4+state5;

What does that prove? What is the difference between adding 0 + 1 + 0 + 0 + 0 and 1 + 0 + 0 + 0 + 0 ?
