DIY BLUETOOTH SPEAKER | Rs 50 MINI BLUETOOTH MODULE
มุมมอง 2.6K3 ปีที่แล้ว
If you have an old computer speaker then convert it into a BLUETOOTH speaker with this module.

Previous video :Powering Nodemcu with 12V DC supply : th-cam.com/video/Igj_LDq4sHo/w-d-xo.html In this video, I have made an experiment on how to add a LED Dimmer circuit to your existing LED Circuit which runs in 12V DC power supply

If you have doubt whether Nodemcu can be powered using 12V DC power source then check this out

Don't throw away your CD ROM motor, instead use it as an Arduino compatible Rotary Encoder
It worked but it is not connecting to wifi point anymore
According to this guy you should connect 120V DC to the board and ground it to your balls
don't worry it works because of voltage regulator 1117c that can take maximum input up to 15v. But for safety you should use less than 10v with good quality power supply.
DON'T DO THIS! IT WILL FRY YOUR BOARD OR EVEN CAUSE A FIRE
Can I use normal mobile charger with 5v and 2A, through the usb port?
yes, you can
to which pin should i connect the 12 volt??
Vin
@@thesrijan49 very thanks
My esp32 board shorted when goving12v
Now unplug it and plug it back in bet you’ll get smoke did this by mistake last night 😅 killed 5 mcu in one night
Bro, Can i use logic level shifter along with esp32 module to detect high frequency square wave having amplitude 5v?And will it affect accuracy?
Thank you
do not do this,mine destroyed after giving it less than 9 volts through the VIN.
same
How u know it's destroyed
This is what happens when you don’t have any knowledge of electricity, you burn your electronics!
DON'T TRY THIS MY ESP32 GOT DESTROYED!!
What happened to your NodeMCU I am getting the fatal error like A fatal error occurred: Could not connect to an Espressif device on any of the 1 available serial ports
my esp32 burnt after put 12v
mine hibiscus also terkorban after putting 12v
you can't do that for a long time.
my 3 nodemcu just destroyed after giving 12v
What happened to your NodeMCU I am getting the fatal error like A fatal error occurred: Could not connect to an Espressif device on any of the 1 available serial ports
Exactly the same thing
Yes bro it is a fully fake video node mcu needs 3.3v constant supply to run you can give it 5v through its usb it has has built in step down voltage regulator so it will run perfectly
Useful tip. thanks for sharing.
please bro make a tutorial <3 i need help
Kaha milega bluetooth circuit
My node mcu destroyed
Ofc it did, the power input is 3v-3.6v and the current is 80mA, am i right guys ?
@@alexandrusandu1249 You can power it with 3.3-9 v no issues ...dont go for 12
@@WOW_EDITING you mean, we can power it with 3.3-9 v from its Vin therminal even the all sources said that the powering range for Vin is between 7v-12v??
Hey my NodeMCU is getting an error like A fatal error occurred: Could not connect to an Espressif device on any of the 1 available serial ports
you are providing 12v AND HOW much current ?
The resistance between Vin and G is 25Mohm, so the current is 480nA
is it okay if i power nodemcu and 5v stepper motor from 9v battery ? (Stepper's max input voltage is 12V)
Yes possible
@@thinkar4873 thanks, will try that
Always use a motor diver. Don't attempt to run the motor directly from the microcontroller.even the motor voltage and microcontroller voltage are same.
Yes this is what iam finding ..❤thnk u
If possible attach circuit Diagram. That will be more usefull.
Good Content. Very usefull.
would be great if upload the circuit and code , i have the motor but i dont know which pin is which
Sure will be updated in the upcoming videos Make sure you get the notification
@@thinkar4873 so, there's no video after all?
Great efforts bro. Try switching over to Raspberry Pi using Python.
Sure and will be covered in the upcoming videos
We can do it using potentiometer easily right....Why making it complex? Please explain the use of this or advantage of it over using potentiometer directly......
This will be explained in the upcoming videos
Name please ???
Very Informative
Do say it as triple 5 timer bro
Need circuit diagram for better understanding
Will be explained in the upcoming video.
Nice try nanba👍
🔥👍
Nice try bro👍
Nice👍
Ethukuuuu 😄😄😄😄
