| Design Methodology |
| Adding a spring loaded hinges |
| Testing the locking mechanism |
| Orale! Wats happenin' Ese!! |
| Keypad & Key entry are additional feature to enter if no power is available for the whole circuit. |
| Back up battery for Key pad entry in locking & unlocking the door. |
| All the circuits are being placed inside, only microphone outside the door. |
| Electronic Relays were used for sending signal to open & close. It's connected to locking electronic circuit of the door knob |
| (VEC) Voice Extreme Microcontroller with microphone & speakers inputs. |
| Microcontroller with a microphone and speakers input. Relays are connected with outpur of VEC-Microcontroller. |
| Left side: Green LED light is ON for setting the command password for the user before going out the door. It activates "Please say your first password". Once the password is set, it would say "Password accepted" and it sends the signal to lock the door. |
| Middle: Yellow LED light is ON for listening for user's command password. If password is wrong it will tell you "password is not accepted, please say your password", and continues to listen with the yellow LED ON and will keep locking the door lock again and again. |
| Right side: Red LED light is ON if command password has matched. It activates "Password accepted". Then, it sends signal to the electronic relay for an impulse signal through the electronic circuit of the door to an open position of the locking mechanism. |
| Voice Control Door Lock will be implemented in any home or businesses for convenience of using individual voice to command the door to open or close. The design is quite simple. The door lock itself is the focus of our design. The locking mechanism will be wired to a microprocessor controller. For locking the door, the user speaks into the door microphone, the user's voice will be stored in the memory for recognition of the password command. For unlocking the door, the user will be asked for his/her password command. If the password command voice is recognized, the door lock will automatically open without using any key or keypad buttons, or basically without using any of your hand. |
