- Say goodbye to keys!
Let's make a simple password-based door lock system using Arduino, a solenoid lock, a keypad matrix, and an LCD screen. It is a very useful project for school and college projects.

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
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...
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.
Can I use Arduino smd
would you please give us the code
It is okay that our relay is single channel (12 volts) and our supply is 12v or 9v?? For project purpose only . Thank you
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
عيد سعيد يا أستاذ شاكر
فيديو عظيم
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 👌
