Lack of proper home security is just is dangerous driving your car among your kids without a seat belt. The world is cruel and offers a lot of risk including home invasion. In fact, recent statistics indicate 500 break-ins in every passing second, there are certain things you can do to secure your home, such as installing a digital lock system. Today, I am presenting Digital Electronic Door Lock developed with PIC Microcontroller and simulated in Proteus. When I was writing its software, the first thing that came to my mind is the password which is the only key to open the lock. The owner of the house must know the correct password otherwise lock will ask for code again. What if someone keeps on trying to attempt the wrong code? Here we need an alarming situation, in that case, the lock will start a buzzer. ☺ It’s fairly clear from the above figure that I have used a PIC Microco...
