Nice
thanks you bro
Good ideas 👍
👌
Nice ✌️♂️
supper idea
Good work
Love they way your work is so neat. There are other designs without a resistor and transistor. Can you please explain why you require a resistor and transistor in this design?
Supperb! 👍
Good job bro t
Nice and neat attachment. And understand able👏
Good
Hay lắm...
Cám ơn anh
Ủa ông người Việt à.
thanks for the great video. Can you plz explain why did you use the BC547 transistor instead of the other ones?? thanks~!
Will this circuit works with 20 feet wire? Don’t think so. If it doesn’t work with 10-20 feet wire then it’s not much useful. Any reasons
I tried with long wires 5 metres and found this circuit failed., giving wrong LED indications... 🤔🤔

Congratulations Bro to complete 1000+ subscribers.
Thank you bro,,,
Thank you
Sir can you say LED +/- You have connected to resistor ? And Transmitter s emitter or collecter you connected to resister ?
sir thanks for the video. can i use 5v (usb connector) to do this proejct?
Yes bro
Serve para óleo diesel?
Are bhai up led ki konsi pin resistance ke sath lagarahe ho
brother instead of using buzzer can we continue the negative wire like that only. PLEASE REPLY.
Den otra opción de transistor al parecer todos los proyectos que presentan en RUclips solo saben usar el BC547,presenten los mismos proyectos con otro transistor...a ver?
como deixar o buzzer para acionar quando a caixar esvaziar?e não quando estiver cheia
Can resistor of high k can affect to grow led
YES IT WILL EFFECT
KEEP LOW RESISTOR 1K
please someone answer, why do we need the transistor, even without them, the water will act as a conductor and connect the positive wire to the led
Can I use the same parts for 12V
and the sensing wire how meter will be long so that no voltage drop will cause ?
Can I use bc 337 transistor? I'd don't have 457
It works without BC547. I did only with 1k resistor, why should I use BC547?
Can I use 12v adaptor?
Yes you can use it
Hello ...can i use 6 volt battery??answer me soon please please
No problem you can use 6V
@@ElectricCreative thank you bro
@@ElectricCreative but can i use 1k ohm risistor
What is the importance of transistor here, what if I don't use transistor ?
make only one BC 547 use in water indicator
Is This circuit can't use commercial?
Can I use 5 volt mobile charger ??? Please reply .
yep,,, no problem
You have collected the battery in series so it will give 10 volts I'm i right
Vai 12 v. Betare deya. Cholobo. 9 bolt bad. Ok. Plz...
Works ok, but led glows lightly, even not submerged in water??!!
Can I use any colour led , as like blue , white etc , please reply .
Yes you can use no problem
What the polarity
my project is not working😭😭 what to do ????
Transistor npn and pnp two working
why you use transistor?
Fuel level k liye b use hoga
Bhai Mera 1000 ltr tank me 9v battery se baj jayega kya
question, will that change the water ph?
reason is because i wanna test that with DWC growing method.
thanks and keep posting vids
Can I use bc 548
How to make rc mini doran
BRO,,, There is a mini drone video, already
Ok bro
How to stop the buzer
Resistor value use
Dont west money led blanking not working
Buzzer sound not work
Can i use adaptor 5v
Yes bro..You can use
Sir This way can I use 12 volt adapter
yes
Nice
Can I use the same parts for 12V?
Nice
