Nice demonstration

[@techathome]

Thank you

Welcome

[@lhanceandrewtambis9839]

Hi, can i ask for the code?, if you have it😔 im asking for it because i dont have money to pay for it... Im making a similar project and i need the code to make some part of the project easy. Thanks for noticing

[@AkyshaRobles]

Hello, it is truly an amazing work and explanation. However, aside from dry, medium, and wet, the LCD also displays dryium and wetium eventhough we did not put it on the code. What appropriate actions shall we do? Thanks!

[@sakshicharapale6589]

Hello brother Actually I am thinking to do this one... How much cost it will take??? And is it working properly?? Plz let me know

[@techathome]

what are the libraries should be installed in that code???

[@techathome]

only LiquidCrystal_I2C.h

[@samanthaagnas3512]

Excuse me , How will this work if I use a battery instead of the usb cable. I’m having problems with the power source , the RX won’t light up. 😢

[@techathome]

Yes you can use a 9v battery with a round pin connector to power the Arduino board.

[@shikaku4257]

can I do this code without the lcd? I have no lcd in my project but aside from that it's the same

[@techathome]

Yes you can do without LCD also. Use same code.

[@jacobjerald6703]

can i use esp8266 for this same code by changing the board in software before uploading ?

[@techathome]

Yes you can use. Refer the pinout diagram of Esp8266 and based on that make the connections.

[@techathome]

You have to install Liquid crystal i2c library. For steps refer this video: kzbin.info/www/bejne/hnennp6wiL1rbdEsi=epQQE7PCuKq-PvP1

Sir, I got the jhd162a display so I don't know how to connect it can u help me to connect it?😢

[@techathome]

You can buy i2c interface module, solder with your LCD. Connections will remain same.

[@Zero-vp4hn]

bro when insert the battery everything goes wrong and it does not work properly i use a 9v brand "EVEREADY" battery

[@Zahra-uo5hr]

how many volt is ur pump. is it 9v or lesser

[@vihaanchavan5630]

Everything is working but the pump does not turn on when moisture is low

[@D.D20]

Same to me, realy and pump are making difficulties

[@koushikkumar2442]

How did you give power to aurdino and lcd screen

[@techathome]

You can use 9v battery and round pin connector.

[@Krishna-ng5be]

Can we use 16×1 Lcd display

[@techathome]

Yes you can use, but some code changes need. All the text I am printing on 2nd row will be not shown in 16*1 LCD.

[@shreyas8082]

hi the code is working properly but the lcd doesnt show statements about moisture. i tried adjusting brightness of lcd but it doesnt work can you some other method

[@techathome]

You can send code photo on mail: [e-mail] We can try reversing relay switching in code once.

[@saratarin4622]

I have a question, what battery should I use if my water pump is 3v

[@techathome]

You can use normal cells(2 connected in series) or if you want rechargeable, you can go with 18650 battery.

[@ayushparate283]

As you connect battery directly for supplying power, then how to do with solar panel ?

[@techathome]

The pump I have used can work with 4 to 5V. So you can use corresponding solar panel instead of battery.

[@wangdedeii910]

hi, if i add on/off button, will the coding be different?

[@techathome]

On Off button for what? Main supply?

You can use any one.

[@muhammadzayn5523]

I have tried if the relay is not plugged into the battery the system works accordingly but when the relay uses the battery the system stops and the LCD appears strange letters or sometimes the LCD turns off the background light, can you help how to solve it?

[@techathome]

I think power is not sufficient. You can power your Arduino board using one more 9v battery and round pin connector.

Relay is used in this video know do we have to use that only or other else?

[@amrithas3351]

​@@shashankhiremath4974you need to use other relay according to the voltage required, if you need to use AC then use 240v or AC relays modules ig

When u remove the soil moisture sensor why the motor starts

[@techathome]

When I remove the sensor from the pot, there will be no moisture. This is considered as Dry according to logic, so it activates the motor.

[@codecrusader123]

can we do this project without using relay

[@techathome]

For DC motor you can also use motor driver instead of relay.
