Thank you very much, friend.
Thankyou this video means alot for our project 🙏🙏🙏
You're welcome :)
It's really working
I tried it in ATL lab
Thank you so much brother!!
Nice work dude 👍
its an amazing video i liked it
It is awesome it really work
Good bro really a good project in easy lenguage
thanks .....we did it....
Can you please provided the circuit diagram and theory on this project
Thank you
can u please upload the circuit diagram
Have you found
how much led can we connect to each emitter of the transistor ,how long can we extend the wire so that there would be no attenuation loss, and how much voltage the emitter gives?
Yoooooo, thk for the video!!!!!
And when I am putting the third LED wire in the water the wire which is connected to the 3transistor base .. it is affecting the perivous two LEDs two
I have to make. The project like if the water level rises the previous light should be off only one light glows at a time.
How to do it? Plz tell me
Hey....I'm making this today....but can we fix the bc547 transistor some far... please reply....and ya...I loved this...thank you for sharing this video wid us
thx bro it helped me a lot for my science exibition
+saurya stha You're welcome bro!
Can male to male jumpers wires be used to drop one end in water
Great sir
Does the 2N2222 transistor work?
Will it be possible if we use thyrsitors instead of transistors?
Bro nice initiative
excellent its working
+shyam mamidi Yup! It definitely works! :D
I did it sir but my third LED is not working and buzzer too can you tell me what to do
Amazing
I love you bro
Hey everyone!
Make sure you check out my latest "Water Level Indicator" video! 👉ruclips.net/video/qWwaH7TaNLU/видео.html
Have a great day! :)
Omg you ar so smart
Super bro 💡💡💡💡👍👍👍👍👍👍👍
Can u do the same scheme but with 5 led and 10 resistors plz
Sir thanks for your reply
+SCIENCE 2NR You're welcome! :)
Can i use lm35dz transistor ?
Can you pls share the circuit diagram of this??
Bro I have a request can you plz send its theoretical work or proteus simulation....you are excellent bro...big fan.
Can I use 2n222a transmitter
hey bro... plz send me its theoratically working principle as soon as possible.. bcz i'm preparing a presentation on this project and i want to know that how it works i.e. flow of electrons in each water level etc.?
Jando bhai 4 saal ho gaye lekin usne kuch nahi diya 😂
Mga bobo ampota, ang dali lang intindihin eh. Mga tanga
Amazing video but can we use jumper wires instead of simple wires as I have to make a project
Yes
Can we use a lower rated Buzzer. All I got is 5 volts is there a way to make that work? Cool vid btw
Nice
Can I get circuit diagram of this?
Thank you so much, I understand it perfectly but there's one thing that because of shadows I wasn't able to see clearly. So it's a humble request that from next videos Please don't let the shadows on the connection it's difficult to understand then.
Oh and by next videos I meant that videos after you read this comment.
❤️❤️❤️
Can we use 220 Ohms resistor
Hey bro can you show me the circuit diagram plz reply
Bro can I get the circuit for this
is it an active or a passive buzzer?
Can I use transistor 220 ohm
working super
Ijaz Ahmed how to determine the collector and emitter of transister
Hello brother please explain with steps of connections done on breadboard i want to make it for my clg project.
Can i get the circuit diagram please
Superb video bro hats off to you
+Yeshes Yash Thanks a lot bro!! :D
Is it working???
Why it may be that the buzzer rings when it is connected...even at the lower water level?
Can I change the transistor with a different transistor with a number bc148. that I have ... but I do not know Emmeter, base, c
+Mohamad Kourdi Hey i don't know if it might work with BC148 transistor but you can try it out!
Also, to understand the collector, base & emitter of a transistor simply place the flat side of the transistor facing you and the 1st pin will be the 'collector', 2nd pin will be the 'base', and 3rd pin will be the 'emitter.'
www.qariya.info/electronics/pages/tanklevel.htm. i want your opinion and is it possible to work circuit .. Because the professor said he wants a circuit is not simple .. But the circuit that you have done wonderful Thank you I benefited from them and I will install in addition to those
Keeping wires in water makes led glow?
How to Battary recharge?
Use rechargeable battery and do this.
Thank you.
330 ohm resistance colur ennathu sir
Hey troy aroujo
You are a Stan and me too
That means we brothers
Even if we don't know each other
+slimshady4eva Yeah bro! #stan4life ! :) Btw its Troy Araujo* :D
Can we use different transistor
Buzzer not working but when i directly touch wires working
From were did u bought all components plz tell
Can u provide the circuit digram
Can you provide a schematic diagram?
Why isnt the positive side of the LED connected to the Collector. It appears to be connected to the emitter.
nice bro..is it can be used also for petrol or gasoline tank ?
Can u send me the circuit diagram of this
Can you please provide the Theory of this project?
Can I get working pdf?
Sir I watched this video many time and I constructed my circuit as shown on video But still not my circuit is not working 😭
Same
it does not work i used 220 ohm resistor but it shuldnt be a problem that much pls help
Bro it depends on the type of transistor u have what type of tranzistor u have
Resister ka plus or negative hota hai kya? Yah fhir jisi tarah se bhi laga ne se hoga
+SCIENCE 2NR There is no such thing as (+) or (-) for resistor.... you can connect it in anyway.. :)
Sir Maine circuit banaya but water Mai Jane ke pehale hi led or buzzer on ho Raha hai.. plz reply
hello bro what can i call to buzzer in urdu
bro, do i need any wire under the breadboard?
Hello, you don't need them and that's why bread board is recommended for Begginers
How to make this in reverse logic? When water is low the buzzer should beep.
heyy, can i use 220ohm resistor instead of 330 ohms?
Yeah no problem
Hello Sir can you plzzz send me circuit Diagram ... Plzz I really need it ...
Bro share the circuit diagram of this
ohh it is good please uploaded circuit diagram
Friend how can I connect it to Arduino?
Sir can u plz give the circuit diagram sir...
Bro can you make a video on wireless Mobile charger
why you connect 4 wires ??
Actually I am connecting the circuit my led is always stop working all time
Sirji,
Jese jese video me bataya he usi tarahse circuit banaya he, lekin circuit bahar se check karte he to barabar salti he, aur water tank me (bilkul barabar) wire joint karne ke bad circuit check kiya to LED pani kam hone par bhi halka glow hoti he, aur koi LED pani kam hone par bhi jyada glow karti he,
To sirji iska kene setting kare thoda batao.......
Awesome !!! 😃👍
Thanks!! :) +Adrien Alves
Adrien Alves ..is it working
+abhiram abhi It works 100%. You can also watch my previous video of 'How to make a Water Level Indicator on Breadboard' :- ruclips.net/video/qWwaH7TaNLU/видео.html
Please send circuit diagram
I have a question what if I remove the water and still there's water droplets that touches the wires, Do they still conduct electricity?
To avoid this don't keep vires attached to the wall of the container
Yes but for short interval of time and not conduct electricity properly,LED will slightly brightens and then circuit will conduct more current.. i have tried it many times but i m confused for the resistance used .
i do this machine but is not working
First it worked but 2time it's not working
Sir starting me 2 led jle and after 5 min 1 bhi nhi
Please clarify about 330 Ohm Resister. When asked about this they are asking more details about the 330 Ohm. Please Clarify the full specifications of the resister. Regards.
+Ram Prabhu
Value - 330 Ω
Type - 4 Band Colour Code System Colour Code - Orange, Orange, Brown, Gold
Multiplier - Brown, 10
Tolerance - Gold Band ±5%
Have a great day! :)
Thank you very much for your quick response.
+Ram Prabhu You're welcome!
instead of BC 547 Transistor got BC 548B as could not able to identify very small letters. Please clarify can i use BC 548B instead of BC 547. Regards.
+Ram Prabhu Honesty i don't know if it may work with BC548 transistor but you can try it out and let me know!
Bro circuit diagram
where can i buy these parts...i am a not an electronics student.....but i am interested...
can you let me know?
+siddhartha bhattacharya Hey! You can buy these parts from ElectronicsComp.com
Here's the link :- www.electronicscomp.com
Troy Araujo thanx
Troy Araujo ok one more thing..is there any certain specifications for breadboards....what is it called,i mean the one you used to demonstrate? or is it that all these boards r similar..
+siddhartha bhattacharya You're welcome! :)
+siddhartha bhattacharya Don't worry all breadboards are similar. There's no definite specification.
Circuit daigram pls
Sir please send circuit and description 🌸
sir we can connect on/off dc power switch
Yes, that would be better!
Which place we have to connect the switch sir???
Sir kya hum 4th transister use kar k buzer laga sakte hai
+SCIENCE 2NR You don't need to use 4th transistor... connect buzzer to the 3rd transistor.. see the video..
TROY, CAN YOU SEND THE CIRCUIT DIAGRAM OF THIS CIRCUIT..
+kushal mr Hey, watch my latest video on "Water Level Indicator" - ruclips.net/video/qWwaH7TaNLU/видео.html
It has the circuit diagram included in the video.
Troy Araujo thank you
I' m using a buzzer in this project without wire , but it doesn't produce sound , do we have to use the Same buzzer which you use in your tutorial ?
It's passive buzzer
Connect the Active buzzer
npn or pnp transistors ?
+Tooba Khan I've used a BC 547 Transistor which is a NPN Transistor!
Troy Araujo thank you
+Tooba Khan You're welcome bro! :)
