I have project to make rfid program for auto lock door, i want to use a pair of 12v solenoid, 1 buzzer, rfid, arduino uno, on button from inside the room,

The schematic is the pair of solenoid will work in the same time when we scan the card to rfid system, but if we open the door from the inside we just need to push on button.

But the schematic is different, i use a pair of solenoid which both are work in the same time when we scan the card, and i use a button from inside the door for unlock, then buzzer will noise every the door open. Could you be my instructure for this project? I'm so glad to hear you say yes
