Clifford Systems JI1000 Car Alarm System

Clifford Systems JI1000 Car Alarm System

Introduction The design philosophy behind the JI1000 is a simple, yet powerful microcontroller based mobile security system. At the heart of the JI1000 is the Atmel AT90S4414 8-bit RISC microcontroller. We used the 4414 for this design because a microcontroller is well-suited for a security system. The basic control functions for our system include monitoring

RFID security system using ATmega32 microcontroller

Introduction and Motivations: For our final project, we designed and built (and exhaustively tested) an RFID-based proximity security system for use with Cornell Identification cards, which have been RFID-embedded since fall of 2003. The idea for this project was sort of spawned from our general interest in RFID technologies and the near-simultaneous occurance of Lab

AVR Security Keypad Lock using ATtiny2313 microcontroller

The Security Keypad Lock Project is a basic access control system based on ATtiny2313. It can be modified to protect just about anything. The “Code Lock” ability will allow the rightful user to deploy the platform to any property that requires simple password-protection. The “AVR” RISC microcontroller used ensures low costs. Possible applications may include:
