Automatic Garden Watering System BY Arduino, LCD, Buttons, EEPROM, Solenoid Valve, Motor and Underground Sprinkler

Now we are making automatic watering plant

I use .5 KW motor which can operate only one sprinkler at a time

so i use this method

which give me positive result

Step 1: Hardware Required

for automation you can add different things i choose Solinoid valve

In this project you will control solidnoid by mobile .

WE will also make it Automatic by timing

if mobile is not present you can also operate with keypad

I also add lcd in the project to see the the present status of Solidnoid switches

hardware required in this project

Android Mobile jumper cables

16 * 2 LCD display

HC-06 Bluetooth Module

Arduino uno or MEGA

Bread Board

10k ohm varible for LCD

Relay Module

For making own relay

Module Relay

Transister Resisters

PCB board

Step 2: Software Required

https://play.google.com/store/apps/details?id=com....

Download this app for automation

it can control 8 relay at a time

Its also have a timer.

To program on arduino use Arduino IDE which is available on

https://www.arduino.cc/en/Main/Software

Step 3: Piping Design

Attach all the solinoid with the pipe in parallel

and attach underground sprinkle in series with solidnoid valve

This digram will help you in pipeing

Step 4: Loading Program Witharduino and Relay Module

in this we only use relay module and arduino

I have 15 minin you can also change

in arduino 1 second is equal to 1000

1 min is equal to 60000

change it according to requirement

<p>int timer = 900000;          <br>int solid[] = { A0, A1, A2, A3 };      
int pinCount = 4;           </p><p>void setup() {
  for (int thisPin = 0; thisPin < pinCount; thisPin++) {
    pinMode(solid[thisPin], OUTPUT);
  }</p><p>for (int thisPin = 0; thisPin < pinCount; thisPin++) {
   
    digitalWrite(solid[thisPin], HIGH);
    delay(timer);
    digitalWrite(solid[thisPin], LOW);</p><p>  }
}
void loop() {
 }</p>

Step 5: Now Adding Start Botton in Arduino

when you press button machine will start at that time

Change the timer setting according to your requirement

1min is equal to 60000 in arduino

change setting according to this

<p>[code]<br>int timer = 5000;          
int solid[] = { A0, A1, A2, A3 };      
int pinCount = 4;           
int sw[]={6};
void setup() {
 
    
for (int thisPin = 0; thisPin < pinCount; thisPin++) {
    pinMode(solid[thisPin], OUTPUT);
  }</p><p> 
  pinMode(sw[0], INPUT);
  digitalWrite(sw[0], HIGH);
  
 }</p><p>void loop() {
  if(digitalRead(sw[0]) == LOW) {
  for (int thisPin = 0; thisPin < pinCount; thisPin++) {
   
    digitalWrite(solid[thisPin], HIGH);
    delay(timer);
    digitalWrite(solid[thisPin], LOW);</p><p>  }  
  }
  }</p><p>[/code]</p>

Step 6: Adding LCD in the Project

NOw i add lcd in the project to see the status of solenoid valve

[code]
#include 
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int timer = 1000;          
int solid[] = { A0, A1, A2, A3 };      
int pinCount = 4; 
int sw[]={6};          
void setup() {
lcd.begin(16, 2); 
    
for (int thisPin = 0; thisPin < pinCount; thisPin++) {
    pinMode(solid[thisPin], OUTPUT);
  }
 pinMode(sw[0], INPUT);
  digitalWrite(sw[0], HIGH);
 
 }
void loop() {
  lcd.setCursor(0, 0);
    lcd.print("M1 OFF");
    lcd.setCursor(8, 0);
    lcd.print("M2 OFF");
    lcd.setCursor(0, 1);
    lcd.print("M3 OFF");
    lcd.setCursor(8, 1);
    lcd.print("M4 OFF");
  if(digitalRead(sw[0]) == LOW) {
    lcd.setCursor(0, 0);
    lcd.print("M1  ON");
   
    digitalWrite(solid[0], HIGH);
    delay(timer);
    digitalWrite(solid[0], LOW);
     lcd.setCursor(0, 0);
    lcd.print("M1 OFF");
     lcd.setCursor(8, 0);
    lcd.print("M2  ON");
    digitalWrite(solid[1], HIGH);
    delay(timer);
    digitalWrite(solid[1], LOW);
    lcd.setCursor(8, 0);
    lcd.print("M2 OFF");
     lcd.setCursor(0, 1);
    lcd.print("M3  ON");
    digitalWrite(solid[2], HIGH);
    delay(timer);
    digitalWrite(solid[2], LOW);
    lcd.setCursor(0, 1);
    lcd.print("M3 OFF");
     lcd.setCursor(8, 1);
    lcd.print("M4  ON");
    digitalWrite(solid[3], HIGH);
    delay(timer);
    digitalWrite(solid[3], LOW);
    lcd.setCursor(8, 1);
    lcd.print("M4 OFF");
  }
}
[/code]

Step 7: Set Time by Using Two Button and EEPROM

Now i add two button to set time

now you can set time by button LCD is present

one button is for time up and is for time down

#include  <LiquidCrystal.h>

#include <EEPROM.h> 

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
         
int solid[] = { A0, A1, A2, A3 };      
int pinCount = 4; 
int sw[]={6};
int st = EEPROM.read(1);           
int swt[] ={7,8};
void setup() {
lcd.begin(16, 2); 
       
for (int thisPin = 0; thisPin < pinCount; thisPin++) {
    pinMode(solid[thisPin], OUTPUT);
  }</p><p> pinMode(sw[0], INPUT);
  digitalWrite(sw[0], HIGH);
  pinMode(swt[0], INPUT);
  digitalWrite(swt[0], HIGH);
   pinMode(swt[1], INPUT);
  digitalWrite(swt[1], HIGH);
  
 }

void loop() {
  int timer = EEPROM.read(1) * 60000;
  lcd.setCursor(0, 0);
    lcd.print("SET Time");
    lcd.setCursor(0, 1);
    lcd.print(st);
    lcd.setCursor(4, 1);
    lcd.print("MINUTES");
    if(digitalRead(swt[0]) == LOW) {
      EEPROM.write(1, st++);
      delay(1000);
      lcd.clear();
    }
    
    if(digitalRead(swt[1]) == LOW) {
      EEPROM.write(1, st--);
      delay(1000);
      lcd.clear();
    }
   
    
    
  if(digitalRead(sw[0]) == LOW) {
    lcd.clear();
    lcd.setCursor(0, 0);
    lcd.print("M1  ON");
    lcd.setCursor(8, 0);
    lcd.print("M2 OFF");
    lcd.setCursor(0, 1);
    lcd.print("M3 OFF");
    lcd.setCursor(8, 1);
    lcd.print("M4 OFF");
   
    digitalWrite(solid[0], HIGH);
    delay(timer);
    digitalWrite(solid[0], LOW);
     lcd.setCursor(0, 0);
    lcd.print("M1 OFF");
     lcd.setCursor(8, 0);
    lcd.print("M2  ON");
    digitalWrite(solid[1], HIGH);
    delay(timer);
    digitalWrite(solid[1], LOW);
    lcd.setCursor(8, 0);
    lcd.print("M2 OFF");
     lcd.setCursor(0, 1);
    lcd.print("M3  ON");
    digitalWrite(solid[2], HIGH);
    delay(timer);
    digitalWrite(solid[2], LOW);
    lcd.setCursor(0, 1);
    lcd.print("M3 OFF");
     lcd.setCursor(8, 1);
    lcd.print("M4  ON");
    digitalWrite(solid[3], HIGH);
    delay(timer);
    digitalWrite(solid[3], LOW);
    lcd.setCursor(8, 1);
    lcd.print("M4 OFF");
    lcd.clear();
  }
}

[cliffburton71]

Hi !!!
Can you share with us what sprinklers/sprayers you use for this project ???

[Masoud123456]

What's your sketch language ?

[Masoud123456]

It seems a wrong on wiring diagram between relay and motor
How motor get commands?

[Evievard]

Hi, thank you for this nice project. I am trying to do it but the app on google is not there anymore. Any ideas where we can get it ?
Also, do you know how to adjust the project if we cannot use wifi but want to plug the Arduino straight through ethernet connection.
Thank you

[nico61]

sorry, I'm a beginner of Arduino, oh mounted the circuit and loaded the sketch, but gives me the following error, how do I solve it?

</p><p> pinMode(sw[0], INPUT);

[RCHAR]

just change this line :
}</p><p> pinMode(sw[0], INPUT);

with this :
}

pinMode(sw[0], INPUT);

[Alan Felix]

Great job.
I am thinking of doing your project but would like to add a small modification. Can you help me?
How could I make the relays activate in sequence? For example, I'd like relay 1 to turn on for one minute and then turn off, so relay 2 would automatically turn on for another minute and then shut down and so on. Thank you.

[FloridaJo]

This app is no longer available or the link is broken. Is there another?

Edit: I found the app, it is here:

[nico61]

Grazie a tutti per il vostro aiuto

[ZámbóJ]

Hi!

Respekt for this project!!! I intereseting and i trying make this projekt.

I have one question for you, please help me:

When i copy the last commands (set time commands) to the ardunio program software, i have one fault: exit status 1: Can't translate for Ardunio/Genuino board.

What's cause the problem?

Thank you very much and best regards:

Zámbó János

[awaiskhawar]

in lcd library i use "," instead of "."

i have corrected kindly check

Thanks for feed back

[kavish laxkar]

keep it up man voted

[awaiskhawar]

Thanks man

[Kenny RobertsonT]

is this possible that i will use 12v pump because my source is 12v from solar energy. for farmers doesnt have electricity

[minimeccanica]

Kenny, certainly it is possible to use a 12 VDC pump, but not with those sprinklers. I'm running a similar project with Arduino, but I use drip pipes which require low pressure, thus allowing me to use a 12 VDC pump which provides low pressure.

[awaiskhawar]

Yes possible.

Relays are attached
You can use 12 to 220 v pump as you need

[Droxz]

nice instructable, keep up the good work ;)

[awaiskhawar]

Thanks for feedback

[jcaroca]

thanks a lot!!! good work, I was looking long time for this!!!

Greetings

[awaiskhawar]

Thanks for feedback
I will more try to upgrade
