OTP BASED PASSWORD LOCKER(ARDUINO PROGRAM+circuit diagram)

In this SYSTEM, we are going to make a smart OTP-based locking system . This smart lock can generate a new password every time you unlock it, which further enhances your security level. This new device is much safer than the traditional key-based system and electronic wireless lock system. If you are still using the key-based system, you are likely to land in a big problem if your key gets lost or stolen.
