Hello, What line in the code controls how long the lock solenoid is energized? beyond a few seconds will burn out some locks. Edit: I see its the line digital write (relay pin, low) delay 2000
12v solenoid lock works with 9v battery?
sirrr , why the code when i uploaded it , there was an error in the code which is the error wrote "keypad.h : no such file directory" whyyy ???
Download the keypad library
Nice project and tutorial. one opinion -if we can hide the password with * symbol it will be more secure..
Weldone momin bhai. Keep it up. Appreciate your work.
Sir can't open code
hi thank you for your work.
i have a problem the relay module keep going on and off after i plug the arduino to pc usb port whats the problem ?(SOLVED)
Sir, code link in discription is not opening
Sir code is not opening
sir can i ask another question ? why the coding when i connect the arduino , the error wrote "failed to connect to ESP32" did u used nodemcu too ?? please answer me T_T
In boards you might have selected esp32 board, make sure you select the proper board, if you are using nano then select nano
what library is the keypad sir ?
Which software are you using for circuit

Bro urgent please help me how many libary we want to download i download liquid crycltal i2c.h
Keypad.h
Wire.h
what ur LCD library u download sir
Superb b sir
Thank you
Sir can't open code
Pilce send sir
Sir, code link in discription is not opening
Me podrían ayudar con el código me marca un error en la página y no puedo obtenerlo
Code is available now
Nice circuit, bhai. But one problem: How can you unlock the door on both sides of that door?
probably the solution is to have switch inside to unlock the doorknob.
Hello sir why when I upload the coding, it has error and it say no function to call liquidcrystal lcd, it has problem at 'lcd begin'
Have you included the library ?
@@MOUNTDYNAMICS ok sir my coding is okay now but when I enter the password, the solenoid not function
Maybe the power to drive the solenoid lock is not enough.
@@MOUNTDYNAMICS sir, I've try but same not function, and I also has asked my lect and he says there's no instruction coding for the solenoid to function hmm
which jumper wires are used m to m,f to f ,m to f
Bro come upload but lcd display showing empty because of y
Is there any hard reset option
Is there a difference with a green background lcd an blue one?
hii sir it's urgent 😫😫😫
please solve my problem
while I am uploading
it's showing
no matching function for call to Liquidcrystal I2c

Have you downloaded the library?
@@MOUNTDYNAMICS yes bro

Sir I am having problem. When I compile the codes this comes (fatal error : keypad.h:No such file or directory # include Keypad h...
Sir I can contact you on Facebook.
sir can I change the battery with an adapter with the same volts?
Code link is not working can u plz send me the code
Hello sir can I get the coding of this project
Hi link is in the description
@@MOUNTDYNAMICS Is that at the code link?
Yes code link it is
@@MOUNTDYNAMICS oraite thanks
@@MOUNTDYNAMICSCode link is not working can u plz send me the code
sir it's urgent 😢😭
please share the purchase link to buy the table cloth
that mean the blue color baground
please please please sir

Sir plz give circuit diagram
Can I use a Oled 128x32
What would I need to change in the code
You got to change whatever has been given for 16X2 LCD and add new libraries
Will be uploading the video tutorial on Oled screen soon
