I tried all the variants that went through my head, I copied from githud I think 15 times, I am at the limit of my imagination 
As you already know, I am not very good at it, so if you are tired of me I understand you …

Sorry Cosmin, some days I’ve got other things I have to do after work. I’ll have a look now…
The thing to know is that Arduino insists on the folder/directory name being the same as the INO file. Since this one is called AutoWater.ino, you must have a folder in your Arduino folder called AutoWater. Then you should copy the files from the GitHub ZIP into that folder so that it looks like this:
~\Arduino\AutoWater\Adafruit_GFX.cpp
~\Arduino\AutoWater\Adafruit_GFX.h
~\Arduino\AutoWater\Adafruit_GFX_license.txt
~\Arduino\AutoWater\Adafruit_PCD8544.cpp
~\Arduino\AutoWater\Adafruit_PCD8544.h
~\Arduino\AutoWater\Adafruit_PCD8544_license.txt
~\Arduino\AutoWater\AnalogReader.cpp
~\Arduino\AutoWater\AnalogReader.h
~\Arduino\AutoWater\AutoWater.ino
~\Arduino\AutoWater\Button.cpp
~\Arduino\AutoWater\Button.h

Where the ~ is whatever the path is to your Documents folder or another folder you may have used for your Arduino projects.
Yes my friend,you saved me,now the code works😊
But i still can t make the lcd works 
I probably don’t have
made the connections
good. I will search the net tonight and i hope i can find the explanation of the LCD and the pins so i can make the coections good.If i don t make it i wil cry for your help again
I managed to connect the wires, the lcd lights up but does not display anything. I think my lcd is not the right one. I ordered just now exactly the lcd in the circuito sketch . When It arives,i make the test and let you know what happened I think in1-2days.
Thanks a lot for your patience 
But i can t make it work:( In the circuito sketch pin 8 of the lcd is sclk on my lcd pin 8 is led…The sketch tells nokia 5110 lcd cs to arduino 3 but i don t have a cs pin on the lcd,my lcd on pin 3 has sce.Nokia 5110lcd sclk to arduino13 and on the sketch the pin 8 of the lcd is sclk on my lcd pin 8 is led,pin7 is sclk on my lcd.If i put no wire to pin 8 led,the lcd does nothink:(
I think sce is cs so i made the circuit but lcd is not working:( If i pun in pin 8(led) the sckl wire then the lcd lights but it is all that is doing,nothing apear on the lcd…
I don t know what to do
Can you save me again?
“Multiple slave-devices are supported through selection with individual slave select (SS), sometimes called chip select (CS), lines.”
This is for an SPI interface: https://en.m.wikipedia.org/wiki/Serial_Peripheral_Interface
My friend, i make the lcd wiring like this: nokia lcd pin1 vcc to arduino 3.3v
nokia lcd pin2 gnd to breadboard gnd
nokia lcd pin3 sce(but on the circuito sketch pin3 is cs)to arduino3
nokia lcd pin 4 rst to arduino 5
nokia lcd pin5 dc to arduino 4
nokia lcd pin6 dn to arduino 11
nokia lcd pin7 sclk to arduino 13
but nothing hapend,if i put nokia lcd pin8 witch on my lcd is led not sclk in to arduino 13 the lcd lights
But it just lights,nothing apear on the lcd:(
I tried and again tried all possible combinations of wires, fail I’m very sad. Do you think neither lcd is the right one?
This is all i can do,but if i use the pin8 on my lcd wich is led not sclk
If i use the sclk pin,but my lcd sclk pin is pin 7 the lcd does not light…

My friend I’m sorry but I came to the conclusion that the circuit diagram can be wrong. Because I have exactly the same lcd as the circuit diagramat .The link above I arrived at,trying to order the lcd from cicrcuito io.It is exactly like mine, at pin 3 it has sce.all the pins are exactly like the pins on my lcd
Do you have any idea why is not working ?
Is it possible to also need a wire to pin 8 led pine?
I had an idea, from the breadboard from 3.3v I took a wire and put it at the 8 led.lcd pin, it lit and vaguely displays the values. In the picture i think you can see.I think it needes some contrast
if it needs a potentiometer for adjusting the contrast, I happen to have one :)Now I have realized that it displays and without powering the 8 LED pine to 3.3v.But so vague …
