I need help in creating the program of an automatic irrigation system with lcd

#21

Don’t just open the INO file from the ZIP file. Windows lets you view the contents, but will not extract the files. You should download the entire source code ZIP file (https://github.com/bernhard-hofmann/circuito.io-4045/archive/master.zip) into a folder called AutoWater.

I’m guessing you didn’t download the ZIP file, or you didn’t extract all the files to a local folder.

#22

I had no unzip file, now I download it and immediately I announce what happened:) thank you very much

#23

i think i did it, but there is an error there and i don t understand what means: no matching function for call ,liquidCrystal pcf 8574…

#24

I copied the library but still the same erorr:(

#25

Sorry, in-laws came for dinner.

Is the error showing when you try compile the program in Arduino IDE? Could you copy and paste the full output with the error please?

For example, my build output shows this:

Sketch uses 6222 bytes (19%) of program storage space. Maximum is 32256 bytes.
Global variables use 579 bytes (28%) of dynamic memory, leaving 1469 bytes for local variables. Maximum is 2048 bytes.
#26

Can you please send me the library LiquidCrystal PCF8574.h?I searched this library on the google and downloaded it(i downloaded others libraries fron google and worked,but this one doesen t:( )Please tell me what to do.Thank you,for your time,and for your patience!

#28

i think this is the error report,it helps you?

#29

Why does your source use greater-than and less-than around the included files rather than double quotes?

Yours:
#include <LiquidCrystal_PCF8574.h>

Mine:
#include "LiquidCrystal_PCF8574.h"

Could you change yours please and try again, or use the code I provided.

#30

I work from a macbook, not windows. Can this be the problem?

#31

I checked in the file again and it s with double quotes, just like yours …so i don t know where the problem is . I am trying to send you a photo …but i can t from here…can you give me an email address or whatsup?

#32

I doubt that the Apple/Windows difference is the issue here. The code you showed in a previous message is different to what I wrote. You wrote:

But that code is not from me. Mine starts like this:

// Include Libraries
#include "Arduino.h"
#include "LiquidCrystal_PCF8574.h"
#include "LDR.h"
#include "Button.h"
#include "Relay.h"
#include "SoilMoisture.h"

As you can see in the Github repository here: https://github.com/bernhard-hofmann/circuito.io-4045/blob/master/AutoWater.ino

#33

You should be able to just paste the image in a reply message. It uploads it automatically - at least it does in the Chrome browser on Windows and Linux.

#34

// Include Libraries
#include “Arduino.h”
#include “LiquidCrystal_PCF8574.h”
#include “LDR.h”
#include “Button.h”
#include “Relay.h”
#include “SoilMoisture.h”

#35

23LiquidCrystal_PCF8574 lcdI2C; I think the error is in this line because it s the only one marked in red

#36

It looks like you added the LiquidCrystal_PCF8574 library in Arduino. There’s no need to do that. If you remove the library, it should find the local copy which seems to have a different version.

Alternatively, you can change the lines to force it to use the local version by adding ./ like this:

#include "./LiquidCrystal_PCF8574.h"

#37

Yes, i will remove it and try again in a moment

#38

I removed it and there is no error anymore. I uploaded the program into the arduino . When i open the serial monitor window nothing appears on it. It should appear something if everything was ok, no?

#39

Excellent!

I removed all the serial stuff. It should show details on the LCD. Do you already have all the components, or which ones do you have?

#40

Beside the light sensors ,i have everything.
