Construction Of A Digital Combinational Lock System

1.4 STATEMENT OF THE PROBLEM
The increasing rate of crime, attacks by thieves, intruders and vandals, despite all forms of security gadgets and locks still need the attention of researchers to find a permanent solution to the well-being of lives and properties of individual.Even with the use of mechanical locks, the crime rate still has increased due to the fact that these locks are easily broken. Consequently, there is a need for other types of locks especially electronic ones. To this end, we construct a cheap and effective security system for buildings, cars, safes, doors and gates, so as to prevent unauthorized person from having access to ones properties through the use of codes.

1.5 SIGNIFICANT OF THE STUDY
Statistics from physical count of existing doors in used here in Mubi shows that only banks use digital locks, few homes (about 1 in 200,000) and few cars (about 1 in 100) use digital locks. Survey shows that the lock is not popular because it is expensive and it is complicated as few people can cram the access code. This work aims to make the digital combination lock cheaper, affordable and accessible for at least 70% for the people in Mubi Town.

1.6 SCOPE OF STUDY
This construction of digital combination lock is based on a flip flop action. We construct a cheap and effective security system for buildings, cars, safes, doors and gates, so as to prevent unauthorized person from having access to ones properties through the use of codes, we therefore experiment the application of electronic devices as locks.
