hi, it would be good if the validated cards are saved in the EEPROM

[dotnetdevni]

Its not storing multiple cards at all ur description is badly missleading

Anyone who has RFID tag can register himself with the door lock system by tapping his RFID tag twice? A burglar can do that too.

Punya saya kalau dipasang selenoid hanya bisa diakses 1 kali, kemudian tidak bisa membaca kartu (tidak ada reaksi). Penyebabnya apa dan bagaimana cara mengatasinya?

[ghaffarmughal]

Can you please do it with servo motor pleaseeee

[ryanbalaguer]

what app you use for wiring diagram plotting

[truyentranhaudio]

Please program the servo controller.
The first time the card rotates 180, the second time it returns to 0
