[@varad811]

bro actually i have connected everything as you shiwed in the video but when i turn on the on switch from my mobile phone for water pump, the relay light emits to green but the pump is not getting started what is the issue?? though i have chnaged the relay twice or is it necessary that the water pump should be 3-12 volt??

[@SayanElectronics]

Yes , pump may not getting adequate voltage it needs to get started...what battery have you used?

[@varad811]

12v

[@SayanElectronics]

But the pump as well as 1 channel relay can't tolerate 12 volts ,they might've been damaged... I have used total 7.4 volts , try using 7.4 volts

sir my nodemcu fit fully on the breadboard so not leaving one point on the edge like u (to connect the led and others component) why is that? did u use the different nodeMCU? or different breadboard?

[@SayanElectronics]

Yes , you are using nodemcu version-3(with CH340 driver chip) , I've used nodemcu version-2 (with CP2102 driver chip)

[@high_voltage603]

are they the same or there is a difference ?@@SayanElectronics

Obviously different , versions , driver chip & size

[@BadarAcademy]

HY Buddy Solve my Issue Please "Compilation error: 'class LiquidCrystal_I2C' has no member named 'init'"

[@SayanElectronics]

some (older) LCD libraries use lcd.init(), but the library you're using needs you to put lcd.begin();

[@SayanElectronics]

Or try uninstalling & reinstalling the liquid crystal i2c library again

[@ELECTRONICS_EVERYTHING]

Bro please help i need a code for only to run the motor(i am not going to use lcd display and soil Moisture sensor...)

[@SayanElectronics]

Do you want to test the water pump or run it with a particular time delay between on & off ?

[@mi0468]

Hello i am also doing this project for final year and blynk app is also works properly but my Motor is not turning on . Can you please help me with this one

[@SayanElectronics]

Motor may not getting adequate voltage it needs to get started...what battery have you used?

[@mi0468]

9v

[@SayanElectronics]

Check the motor separately if it works perfectly or not , bcz the motor can tolerate 3-6V DC . For that reason ,I've used 7.4Volts battery . Also before using ,I drained excess 1V in it in other circuits.

[@mi0468]

Ohh ok I will try that

SIR , what app did you use for the coding part? im so confused, i've downloaded the code link but i dont know how to put the codings. please help me , i need to submit this project this week

[@SayanElectronics]

Software - Arduino You can download it from official " arduino.cc "website

[@imstewpit7885]

hi sir i dont find the followings in the libraries that you showed: 6:32 and 6:48

[@SayanElectronics]

6:48 is not a library it's the board required 1)Open the Boards Manager. Go to Tools > Board > Boards Manager… 2)Search for ESP8266 and press install button for the "ESP8266 by ESP8266 Community" 6:32 is the "ESP8266 Wifi" Library , go to Sketch > manage libraries & then install the library first

[@varad811]

Is it necessary to connect it externally with power bank?

[@SayanElectronics]

No brother , you can also use mobile charger or any power supply box with 5V output supply & also a 5V battery...

[@nesrinehand2796]

Can use the USB cable with my Pc​@@SayanElectronics

[@SayanElectronics]

Why is my pump not working even though the yellow light in the on relay module is still on, the blink app still works?

[@SayanElectronics]

Please tell the battery voltage & amp you are using ...the pump may not be getting the voltage & current to start

[@omkardalvi8484]

Hey I am having the exact same issue as I have a 9V battery.

[@SayanElectronics]

Try using a 6V-7.4V battery. Also check separately, if your pump & relay are working or not

[@jjempoy0854]

Same problem for me, relay module works (tested separately). Pump works when it is connected to the breadboard but not working when connected to battery (7.4V). Please help.

[@chadchampion3700]

Do we need to pay in the Blynk website or you are using free ?

[@SayanElectronics]

No , it's free brother .... For some extra buttons & features it's paid version...but if you follow my video , it's made absolutely free of cost on BLYNK side

[@mathankumarh3458]

How to upload code many errors

[@SayanElectronics]

Code errors may occur if you've not installed all libraries required for the code..

[@SayanElectronics]

Check the relay & each module you are using separately, if they are working , also check the pump, if it is getting proper voltage output from relay out pins...if they are all fine.... Check if your connection are same as that of code ...otherwise it will not work

[@mi0468]

Hey does your motor work properly now ? I am also having the same problem with my project

[@我没有名字哦]

Sir can i use LCD Display instead of LCD With 12C

[@SayanElectronics]

Obviously but in that case you've to define each lcd pins in code & connect separately & that may lead to loose connection giving rise to sevaral problems ...so try to use i2c

[@aritraonyt]

sir can we use 9v hw battery

[@SayanElectronics]

No, the pump motor voltage limit is 6V

[@amelha5494]

Is there any other way to make it without Arduino and breadboard?!

[@SayanElectronics]

Why not , you can make permanent connection in veroboard ... & for more professional design you can use customized PCB

[@egyptian6930]

Do this has limited range?

[@SayanElectronics]

Yes about 2-3kms ...but thanks for commenting😊...I'll make a range test experiment on ESP8266 for my KZbin family❤️

[@kintanvarma8279]

Sir ive problem, my display(led) is turning off after few minutes of usage its not showing any value except light and also data from soil moisture sensor is alsways changing even if its in open air its showing 100 please revert back

[@SayanElectronics]

Please check for any loose connections & check also battery voltage if you are using the same code of mine

[@pancitmiki_01]

Is it still gonna work if i remove the soil moisture sensor

[@SayanElectronics]

The mechanism of the working is that when soil is moist then nothing'll happen but when soil dries , moisture sensor senses it & waters the plant Now , if you not use the sensor , then in code u can use delays to water the plant twice everyday like that...you've to make changes in code to make it work without sensor

[@kuwarprashant967]

Can i use Esp8266 ch340 instead of Cp2102

Download the LiquidCrystal_I2C library , then reopen your Arduino, then try to upload the code again..

[@sogandrostamzade]

can somebody help me?

[@SayanElectronics]

Make sure you have connected your esp8266 (version 1) with computer via USB cable & select the right board & settings as I've done in video at 6:10

[@sogandrostamzade]

i did it but again i cant select port @@SayanElectronics

[@ryucerie]

change the "init" to "begin"

[@DEIX_REMOX_YT]

@@ryucerie tried bro but not working at all

[@ryucerie]

@@DEIX_REMOX_YT you have multiple libraries, only choose the second referred in "not used" . you can delete the one referred in "used".

Install the Blynk library first brother..

[@SayanElectronics]

Select the write board as I've selected ...also change the template id & name . Your BLYNK should generate a different Template id & name . Put that in code .

[@sharathreddy3073]

I selected nodemcu 1.0(ESP-12) I gave what u told in video but it is getting error

[@SayanElectronics]

See carefully there are two options -- 1) NodeMCU 0.9(ESP-12 Module) 2)NodeMCU 1.0 (ESP-12E Module) Option no.2 which has (12E)written, select that board & also go to File > Preferences > Additional board manager URL's & paste this link given below -- arduino.esp8266.com/stable/package_esp8266com_index.json

[@Jobayer.AlHasan]

where is the code ?

[@SayanElectronics]

Code link given in description..

[@hahahagrrr]

can we use the app offline?
