Aim:
The aim of the project is to build security system using Bluetooth technology.
Description:
In this project, the lock has a keypad for entering combinations, a random access memory (RAM) into which the entered data is loaded, a microcontroller, and an electrically erasable programmable read only memory (EEPROM). One or more entry codes for Opening the lock are stored in the EEPROM and loaded into the RAM when the lock is powered-up.
To open the lock, one of these codes or a master entry code must be entered at the keypad. Each entry code can be individually prevented from opening the lock by entering a corresponding individual lock-out code. All these entered lock codes are compared with the stored lock codes which are already stored in EEPROM. If it wills matches the entry will be accepted. This system is works only for our specified EEPROM memory. When replaces that EEPROM with another one it can’t work.
This is done through wireless communication by using Blue tooth technology. At the transmitter end the code is entered and compared with the stored lock in EEPROM and at the receiver end the lock will be received by the receiver and decoded, if it is matches it will allow the person to go by open the door using stepper motor.
Technology:
Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmission over short distances from fixed and/or mobile devices, creating wireless personal area networks (LANs). Bluetooth provides a way to connect and exchange information between devices such as mobile phones, telephones, laptops, personal computers, printers, GPS receivers, and video game consoles over a secure, globally unlicensed Industrial, Scientific, and short-range radio frequency bandwidth
