I have a safe that is locked only by means of a passcode which I enter using a keypad. I do not think that it is safe enough to store very important things. I would like to attempt to create a safe box that will be secure enough for my valuables.
This is my Safe Box prototype. It can be unlocked by a keypad passcode or a RFID keycard. The locking mechanism is powered by 2 metal gear servo motors. The whole system is controlled by an Arduino. Step by step instructions are also clearly shown on the attached LCD screen to ensure user friendliness.
4 by 4 membrane keypad
1602 LCD with I2C
I like that the safe box looks the way I like it and it is easy to use, and can be opened easily. There is also instructions that I like which makes it easy.
For the next prototype, I would like to add on an alarm buzzer activated by a vibration sensor. This will help detect unwarranted access and deter potential thieves.
