This project sounds perfect and excellent, appreciated> Your channel is the top best one on youtube, I will recommend it for all those who are interested to learn and be professional electronics technicians .Many thanks and gratitude

Sell us your pcb

What is the components for the blue one

What is frequency of oscillator.

Where is your CAD file.

Thanks for your hard work its very useful ❤

the resistance connected ti 555 timer ic in 7 to 6

I need one

Something inside me screams in agony when I see "+12VDC" going via a speaker's voice coil. I assembled this circuit myself and there is a VERY noticeable offset in the speaker cone... is there any way to eliminate that? Or change the design so the supply voltage doesn't have to go via the speaker?

nice editing Mr.Electricity

Why in hell do I want to connect to some website that I don't want to???

Brother, please give the circuit design, I can't understand anything from here, where are the registers placed

Can the data send to esp32 ?

What is the name of the wire u used to detect fire

I loss my time with this video shit

Where is full description sir ??

sir how did u installed the buzzer i didn't get it on which port u connect the buzzer can please clarify that

First comment from tamilnadu❤

dear lord, it's eclipse coming to haunt us form the past

Turns on but doesn't go off, why?

Where can I get the PCB for this project?

can you give the code for Assembly?

That's very wrong this project is not aworking i think this is fake and you just màke videos for some views

what does he did in the last part to run the fan

Have you done , Any project related to mobile loss prevention using Bluetooth module... Plz give me some idea

its working thank you so much!!!

what library you used in Modbus - Arduino Tutorial ?

Very useful, needed this for proper visualization, thanks!

are they really the right transistors the noise and switching characteristics are not ideal. wouldn't a BC550 would be better suited for this?

Nice! Could you make a similar project video, where it has 4 push buttons which control 4 relays, on the receiver side?

Code is not complete . Missing index.h library

It's a shame it has PCB schematic NOWHERE to be found, i expected the sponsor link to do that, but it just starts with an empty order and no PCB for this kit.

can a pt-100 be used instead of the lm-741 ic ?

Good

also thermistor connection is wrong you have to connect it directly to pin 2 of lm741 and other end to negative terminal of battery and the other end of 4.7kohm resistor to positive terminal of battery

also whts the rating of each resistor?

the diode isnt required i feel

P r o m o s m 💥

Thank you but Where can i get the pcb layout?..please reply.

Hello sir, I need help, I have 808nm 200mw laser diode and I make simple driver circuit board to watch Google but it doesn't work.can you give me suggestion or diagram how to make adjustable laser driver circuit board for this laser diode.

We're is the circuit daigram

hello please help me out the buzzer starting when am connecting the battery

Very good, it is and test 3A. Ok

Is this working?

Can I use NPN transistor (PN2222) and a 5k ohms resistor?

how did you make ur condenser mic like that, with long tail

Good day sir I have tried to follow the schematic diagram but the buzzer is not turning off after the fridge is closed. Can you help me please

Quick question what if i want to add resistor and the value

why not just plug the sensor into the pcb ?
