Can you please provided the circuit diagram and theory on this project
It's really working
I tried it in ATL lab
I did it sir but my third LED is not working and buzzer too can you tell me what to do
Thankyou this video means alot for our project 🙏🙏🙏
You're welcome :)
Thanks sir !! They are working ❤
can u please upload the circuit diagram
Have you found
not yet @@iremyilmaz029
I love you bro
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
Thank you so much brother!!
thx bro it helped me a lot for my science exibition
+saurya stha You're welcome bro!
Super bro 💡💡💡💡👍👍👍👍👍👍👍
It is awesome it really work
330 ohm resistance colur ennathu sir
Thank you very much, friend.
Bro I have a request can you plz send its theoretical work or proteus simulation....you are excellent bro...big fan.
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
Bro nice initiative
Can we use transistor BC 548 and resistor of 220 ohm
Superb video bro hats off to you
+Yeshes Yash Thanks a lot bro!! :D
Is it working???
Yoooooo, thk for the video!!!!!
Hey everyone!
Make sure you check out my latest "Water Level Indicator" video! 👉ruclips.net/video/qWwaH7TaNLU/видео.html
Have a great day! :)
How have you fixed the buzzer ??
Like have u used nails if yes then how did u put it in bread board?
Good bro really a good project in easy lenguage
nice bro..is it can be used also for petrol or gasoline tank ?
Can we use 220 Ohms resistor
Why it may be that the buzzer rings when it is connected...even at the lower water level?
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.
❤️❤️❤️
Thank you
Can you pls share the circuit diagram of this??
excellent its working
+shyam mamidi Yup! It definitely works! :D
Can I use transistor 220 ohm
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
Amazing video but can we use jumper wires instead of simple wires as I have to make a project
Yes
Can male to male jumpers wires be used to drop one end in water
thanks .....we did it....
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?
Nice work dude 👍
Does the 2N2222 transistor work?
Can I use 2n222a transmitter
Keeping wires in water makes led glow?
woah...nice but, do we get electrified if we touch the water in that state?
Haha nope you won't get electrified don't worry! Plus this is not alternate current.... It's direct current .. so its safe :)
its an amazing video i liked it
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
Sir Maine circuit banaya but water Mai Jane ke pehale hi led or buzzer on ho Raha hai.. plz reply
Sir thanks for your reply
+SCIENCE 2NR You're welcome! :)
We can used 1K resistors
Why isnt the positive side of the LED connected to the Collector. It appears to be connected to the emitter.
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
Can you provide a schematic diagram?
sir we can connect on/off dc power switch
Yes, that would be better!
Which place we have to connect the switch sir???
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.. :)
Can we use different transistor
How to make this in reverse logic? When water is low the buzzer should beep.
Can i use lm35dz transistor ?
Can u do the same scheme but with 5 led and 10 resistors plz
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
Sir please send circuit and description 🌸
Hey bro can you show me the circuit diagram plz reply
Will it be possible if we use thyrsitors instead of transistors?
Amazing
Hello brother please explain with steps of connections done on breadboard i want to make it for my clg project.
You should connect the buzzer to the anode of the LED NOT to the transistor base.
Unhappy about this video.
True
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
Actually I am connecting the circuit my led is always stop working all time
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
working super
Ijaz Ahmed how to determine the collector and emitter of transister
Friend how can I connect it to Arduino?
heyy, can i use 220ohm resistor instead of 330 ohms?
Yeah no problem
is it an active or a passive buzzer?
Great sir
Can we use a lower rated Buzzer. All I got is 5 volts is there a way to make that work? Cool vid btw
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! :)
can we use 220 ohm resistor
+TECH SERVICE Yes!
thanks ! it deserves a like
+TECH SERVICE Thanks bro! :D
+TECH SERVICE Thanks bro! :D
First it worked but 2time it's not working
How to Battary recharge?
Use rechargeable battery and do this.
Thank you.
Can u provide the circuit digram
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.
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
hello bro what can i call to buzzer in urdu
From were did u bought all components plz tell
we will not get shock na if we touch the water
ohh it is good please uploaded circuit diagram
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
Can I get working pdf?
Omg you ar so smart
Bro can I get the circuit for this
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.......
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!
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
where do u buy the components for it?
+Hirak Desai You can buy them from Amazon,EBay or any electronic store in your locality!
why you connect 4 wires ??
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..
Bro can you make a video on wireless Mobile charger
Can u send me the circuit diagram of this
I tried this, but not working.
i do this machine but is not working
It is not working guys if u are making it for school project than drop it looked ezzy but not works!!!
Can you please provide the Theory of this project?
Nice
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 .
