A digital voice recorder (DVR) is implemented on a field-programmable gate array (FPGA) using Verilog hardware description language (HDL). The board’s RS-232 port is used to interface the DVR with a computer. Control of the DVR is available through either the board controls or the interfaced computer. File transfer between the on-board memory and the computer is also facilitated by the serial port interface.

     The project is a development of a previous project that designed and characterized a two-motor three-wheeled robot that uses odometry. The limitations of the project were removed by using a new Borland Turbo C++ Program under the Windows 98 platform. This new program has better errorcorrecting algorithms and improved the robot’s movements. The robot was made to move in all directions, and a new feature that allows the robot to move by itself using user-specified coordinates was added to the previous manual control. The accuracy of the rotational movement was tested from 0-315°, with increments of 45°. Moreover, an additional feature that made the robot move using data that served as way points from a text file was also added.

     Mighty Mouse is a system implemented using Visual C++ to control the movement of a cursor based on the images captured by the system’s camera. The system includes a hardware, composed of the web camera and the LED-based device, and a software, which is the program that controls the web camera, analyzes the images taken, and detects the movement of the cursor.

     This paper discusses research done on interfacing a computer with a sonar and stepper motor setup to create a three-dimensional sonar detection and control system. The system follows cylindrical coordinates and has been tested for a small volume with radius approximately 35 cm and height 25 cm.

     This project presents a design and implementation of a barcode and keypad access system specifically for the rooms in Faura Hall. A computer is interfaced with a relay circuit in the door and consequently controls all accesses and logs to the system. The input of the system will come from a barcode scanner and standard keypad, which are connected in parallel through a port splitter. The splitter is then attached to the keyboard port in the motherboard of the system computer. Circuitry is minimal and the user interface is simple and flexible for operation by the user. This project, however, is software intensive. Software design was carried out in C/C++. The barcode and keypad access system provides a database for allowed users, as well as, a smart logging algorithm, which keeps track of a user log-in and blocks attempts to enter the same code once the user is already inside.
     Essentially, this project serves to enhance the current keypad door access system, wherein an additional barcode scanner obtains the user’s school identification number. The keypad entry, further assures the identity of the user. The PIN, or personal identification number, is not to be divulged and is known only by the specific user and, of course, the administrator or instructor in charge of the system.

This project aims to create a program that will display the RGB values of an image. Moreover, the control variables that will give an accurate image of an object is obtained.

A remote control of appliances is a system that enables a user to manipulate the performance of home appliances without direct physical contact with it. Usually remote controllers use infrared to transmit information but the required maximum distance of the appliance and the user poses a limitation. With the popularity of Short Message Service (SMS), and the large coverage areas of mobile phone service providers, this range is extended considerably. Control through SMS is realized by connecting a SMS-capable mobile phone to a computer's serial port permanently. A Visual Basic (VB) computer program reads a request from the SMS received by the attached phone and turns on or off the corresponding appliance via the printer port.
