  1. 1. INTRODUCTION <br />Group members :-<br />Ahmed TauseefAffan<br />Syed Abdullah Shah<br />Yousuf Abdul Salam<br />
  2. 2. 4 DIGIT SECURITY KEYPAD<br />
  3. 3. OUR AIM<br />The basic aim of our project was to familiarize ourselves with the circuit elements that we study in our course on practical basis.<br />Secondly by completing this project we were looking forward to gain experience that will help us in our future works as electronics engineers.<br />We also desired to get familiar with some new circiut elements such as IC, relay coil etc that will help us in our coming studies.<br />
  4. 4. Elements used in our project<br />Capicitors 100 nF<br />Resistors 27k , 4.7k , 2.2k<br />Cmos 4081 & Skt<br />Transistors BC 547<br />Relay SPDT/SPCO(270R coil resistance) <br />LED<br />Buzzer<br />Yousuf in hard bargain.<br />
  5. 5. Assembling of the circuit<br />We made a demo of the circuit on the breadboard<br />But assembled the final circuit on the veroboard<br />Because of its wide range of applications.<br />Also by using the veroboard we looked forward to<br />Get ourselves familiarized with the working of the <br />Veroboard.<br />
  6. 6. CIRCUIT DIAGRAM<br />
  7. 7. WORKING OF THE PROJECT<br />
  8. 8. APPLICATIONS <br /> There are a lot of practical applications of a security kepad some of which are described below :-<br />It can be used to enhance the security of our research facilities by installing the device at the doors of important areas.<br />Likewise banks can use the device for their security purposes.<br />Almost everything that demands a private security can take advantage of the security keypad.<br />
  9. 9. CONCLUSION<br />Finally we conclude that working on a project may be a tiresome job but it enhances our practical skills as well as polishes our concepts on practical basis.<br />It also helps us in realizing our innovative abilities.<br />
  10. 10. THIS IS WHERE WE STARTED<br /> THANK YOU<br />For further information regarding our project please visit our website <br /> www.projectaja.webs.com <br /> AT THE ENTRANCE OF COLLEGE ROAD<br />
