The lock was developed using Arduino, a solenoid lock, and a bluetooth module (esp32) and a Bluetooth SPP (Serial Port Profile) app to communicate with the bluetooth module. I used this tutorial to help develop this lock.
This lock was developed using a solenoid lock, Arduino, and we use tags that are based on the MIFARE protocol and the MFRC522 RFID reader. I used this tutorial to help develop this lock.
