No, I think some relays work differently so you have to set the relay pin to HIGH under the setup function to disable it Then if password is right you set the pin to LOW which activates the relay.
Or is there any code for relay to add a code from ur discription? Beacuse our project is working but the only problem is in the solinoid lock and in the relay. Thank youuu hoping for ur response

which c compiler u used?
Will it work with changed password once it is switched off and on again? If answer is no then it is not for practical use.
Yeah
Does the library really matter from wich programmer it is? I found the Liquid Crystal I2C but it wasnt from Marco Shwartz
It's gonna work but you need to check the documentation of the library
this works great but when you loose power and rer instate power the relay clicks in and out so the door will unlock with power interuption...

Can I use Arduino smd
It is okay that our relay is single channel (12 volts) and our supply is 12v or 9v?? For project purpose only . Thank you

would you please give us the code

Brother, where is coding?
github.com/Enjoy-Mechatronics/Password-Door-Lock
@@EnjoyMechatronics library is missing . not even in github
I don't think it's a good idea to display the password for your door lock. Instead, display an asterisk..
Thanks 👍
Not working he is giving us wrong Code don't try it waste of time
No the code works fine 👌
