The project goal is to build an electronic door lock based on Arduino and ID-20 RFID reader. This security system consists of 3 main parts, Arduino controller, RFID tags Reader and electric door lock. The RFID reader is located outside of the door and is separated from the controller on the inside so no [...]

The Simple Wireless Security System is a security system that includes a ZigBee wireless door sensor and a PC interface. The door sensor mounts near the garage doors, and it detects the open/closed state using reed switches and magnets. The Atmel Attiny45 microcontroller fits in nicely with design because of its small size, low [...]

The Lord of the Keys is password managing system that able to store many usernames and passwords inside a Java Card™ smart card (one of the most secure methods to store confidential information). Whenever a dialog box appears in an application or web browser requesting a username and password, these security features can be [...]

This is an embedded intelligence implanted into the automobile, a cognitive system that gives the vehicle some sort of an entity. The primary function of this entity is to assess driving attitude by keeping a watch on the driver stability both mental and physical, observing the driving patterns to arrive at a decision through a [...]

This vehicle security system built using Atmel’s Atmega8 AVR microcontroller, Analog Device’s low cost acceleration sensor ADXL311JE and Dallas semiconductor’s DS1973 iButton. The circuit powered by small battery power supply which is integrated with the unit.

This laser tripwire project allows you to twittering and grab an image from a webcam or execute any command in a bash script when someone crossing the tripwire. The project construction is simple, you just need to position Laser pointer and LDR in a fixed position, then bounce the laser to the LDR with a [...]

This AVR AT90S2313 based project modifies a home’s existing doorbell to become a hidden keyless entry system. The doorbell will operate normally unless a secret code is entered via the doorbell button. When the secret code is entered, the doorbell does not ring and the garage door is opened.
