Supper sir. Thanks sir.
Thank you, 😊 Keep watching
hi what if i want to connect it to a OR quad? plssss reply i beg
Sorry i didn't get you
@etechniques I mean like not directly to the LED. Connect it to an entry of an OR quad, and the exit of the OR to the led
@yr9829 using ic like 7432 ? Could you please tell me about the purpose? still i couldn't understand your idea 🤔
@@etechniques my circuit consists of two sensors, both connected to the OR, so that when either of those get activated the led will turn on. One of those sensors is this one. So I was wondering if I should connect the collector or the emisor to the entry of the OR.
@@etechniques yes yes 7432
Battery backup achha nahi he 10-15 minutes chalata hai
Dear friend , please understand, I am not selling and promoting this product. I just bought this for my use. I'm satisfied with this product 🙏🙏
Sir components list and price
Circuit schematic in the description Please open the description ...
What did you sold with screw ? Please respond me
Ferrite bead. You can find it from SMPS
Hie where can i order this LCD display
AliExpress
what a nice idea to built the adjustable core !
Thank you 😊
Please help me make a schematic circuit on Easyeda 🥺🥺🥺🙏
I have added the schematic circuit to the video description. Please check it out.

How to fix a multimeter: Step 1: Buy a new multimeter to fix the old one😅
If i use a 5V buzzer and im using for the circuit a 9V battery it wouldnt damage the buzzer or any other part?
Connect a low value resistor ( 100....220Ohm) series with the buzzer.
you solved my problem,thank you soooooooooooooo much my brother😊😊😊😊i really appreciate this video
Thank you 👍
Bro where can we add a switch in this circuit pls tell

can i have a circuit diagram plsss
Sure

TQ So Much.. Even it's not expensive to Buy a New One but U Guide & Show hoe to Fix it.. Now my Multimeter working as Normal.. Keep Up the Works!..
Ótimo?
Sir, mastec mas830l ka original led display board or motherboard market pe milte hai alagse ?
I think no.
Plz full name of sensor n availability?
Magnetic float switch.

Batery backup jyada n h iska
nice
great...
Sir how to caliberate mastech it shows resistance 0.7 ohm on it
.7 Ohm reading in 200-Ohm range is normal
good sair
ये कैसे पता होगा की फुल चार्ज हो गई है
There is no indication, Recharge the torch for 30 to 45 minutes..
i don't see a depth stop on this
Who developed this project first broh
I might have done it 🤔
Can i use potentiometer meter 10k instead of Variable resistor 5k
Yes.
Sir but it is not working based upon temperature, causally when we connect the power supply, the fan automatically starts rotation and also the bulb glowing.
@@vishalgowtham6351This is a comparator circuit using an operational amplifier Check the voltage on I.C pin-Three. Then set the voltage of I.C pin-Two .02 voltage more than pin number three. Example: if voltage ofpin-3 is 5.V, Then set pin 2 voltage to 5.02V ( use the potentiometer for adjusting)
@@etechniques sir getting same problem by using LM358.

amazing!
yes
What is the work of that CD FD
That's the temperature switch wiring pins
@@Bot2.0-p1d thank you for your comment but that pin was directly connected to MOSFET pin for turning on and off

Aapka video lajawab hua hai per Mera ismein DC rechargeable system Kiya hai voltage adjust karke Diya fir bhi wrong voltage show kar raha hai kya problem ho sakta hai
My multimeter is doing same thing.. and it is the same model
Hey,can you give the components required list and it's range and quantity.plz
components list and circuit diagram are given in the description..😊. ( This is a simple transistor based hobby circuit for learning.. 5...10cm is the range)
What is the yellow thing used?
Connecting wires
it isnt working, i triple checked everything, can i have some tips?
Sorry about my late reply. I have checked the circuit schematic i couldn't find any mistake on it. How did you test the circuit ? On breadboard or soldering? You used the same components as I have shown in the circuit?
i checked everything and it looks clear to me, just incase i missed smth about my basics. Does the type of transistter matter I used a mosfet and some transistters
@@synctax1017 yes the transistor are very critical. You should use the same transistors for working the circuit.
@@etechniques I never knew, Thanks for your patience and your useful information. Enjoy your day!
@@synctax1017 thank you.. 😊.
As soon as I connect the battery Led lights up and buzzer beeps not when i spark a fire I have used Ir photodiode but still can you help
1.Please check the polarity of the photo diode. ( Anode to base and cathode to positive) (If not solved do the 2nd step) 2. Remove the photo diode and connect to the power supply. If the buzzer beeps without the photo diode, the problem may be with the transistor or wiring issue.
I have checked the polarity its correct and after removing the photodiode the buzzer doesn't beep. So what can be the issue still I am having same provlem
Mas 830l multimeter में दो रेजिस्टेंट फ्यूज जल गए है उसे कैसे हटा कर replace किया जाये कृपा इस पर नोटिफिकेशन भेजो
Please mention the legend mark of burned resistor
Nice bhai
Magic, got it
Can you please please please tell the type of transistor used and the capacitor used and the values of resistors used and the power supply (basically provide with a circuit diagram)

Which variation of photo diode you used?
Any 3mm or 5mm photo diode
sir woh do jumper wires kaha lagaye aapne ?? plzz tell
You mean on the top side? Those two jumper wires on top are connected to Supply positive. And the other two jumpers (one short and one long) are connected to Supply Negative. Thanks for watching my videos😊👍👍
sir i am talking about that one red one and the other black one@@etechniques
@@itskrishnalive Red and black wires are Supply positive and Negative wires
sir 100 ohm ke jaga 67 ohm ka chalega ??
@@itskrishnalive yes you can use
Please give me contact number
I want to create a major project for my final year can you help?

Is it works in light???
If the light contains more infrared, otherwise not. 🌞🌞🌞This circuit senses sunlight
