Project Title
Laser Security System
Abstract
The Laser Security System allows to maintain security in a room by shining a laser across a door's entrance and alerting via bluetooth communication by sending a text message to a smart phone that security has been compromised.
Objectives & Introduction
This security system will be using GPIO pins from the SJSUOne Board to connect to the RN42-XV Bluetooth Module using serial communication and another pin to the Arduino. The two bluetooth modules each connected to a SJSUOne Board will communicate with each other sending a message via text message using the Arduino module alerting that security has been compromised.
Objectives for this project:
- Research and design the schematics to connect a light detection circuit to one of the SJSUOne Board and showing the output by lighting an LED
- Research bluetooth communication and implement it to the light detection circuit
- Complete hardware design
- Test functionality of the system
- Able to send and receive text messages to smart phone via bluetooth
- Detect and connect to other bluetooth devices
