| Summary: | The project is about the electronic lock using the IC’s timer, SCR ( SN101),relay and push button switches and the other components. We use two IC’s timer (555), which operates m the monostable and astable mode. The push button switches is used for the combination lock. The code used cannot be changed easily, once a wrong switch is operated, the relay cannot be energized even if the right switches are pressed immediately thereafter and this will giving an alarm. This project is important in the security agencies or company. Moreover we can produce the new term of the electronics lock devices to make the easier and controlling the system very professionals |
