Great video.. Kudos to the clear explanation.
I would like to understand one point for my project (not door lock, of course). As in the video, when the RFID activates, we can give an output signal for 5 secs and turns off, right? My requirement is, upon activation, the reader must not sense again for a particular time, which can be provided by a 12V busy signal from the machine. So, once the busy signal is removed by machine, RFID reader is ready to scan again.. Could u pls advise.

Can we use OLED display

[@matejherich6777]

please tell me how can i connect lcd display without 12c module?

[@sascories]

Can i also add fingeprint sensor along with the RFID? If so will I need another relay to power the fingerprint module?

[@EnjoyMechatronics]

Of course!

How​ can​ i​ add​ a​ new​ card​ and​ remove​ card

Can u make door lock by fingerprint sensor please?

I can't find the library for the LiquidCristal by Marco Schwarts. What other can I use. I have all the wiring right but can not read any card nor my display shows nothing. Any ideas?

sir but im using arduino mega 2560 can i know that the coding is ruuning for my arduino or i need to change it.

[@EnjoyMechatronics]

You only have to select the board name and the port of the USB cable.

And how to open it from inside the house

[@EnjoyMechatronics]

You could use the 💳 card or add a push button to open the door from the inside

[@pannawatangcheewanont7827]

can i use esp32 as Arduino Board

[@EnjoyMechatronics]

Yeah
