Access all project ideas / topics that depend on a desktop, laptop or tablet computer interface for their operation. These projects are based on the use of serial, parallel, bluetooth, WiFi and USB interfaces to a computer for extended functionality.
This project demonstrates the use of the Universal Serial Bus (USB) of a computer to monitor and control home and office equipments in order to deliver quick status information, accurate timings and convenience. We explore the use of the HID and CSC USB classes for this purpose.
Voltage, current and resistance measurements can be taken with ease compared with a regular multimeter. The features of a digital multimeter are carried out by the use of the computer’s data logging and Plotting advantage. Interface with the computer is through USB. This allows for a fast connection and compatibility with most modern computers.
A computer software based security system project that uses a webcam to keep watch on a vicinity. It utilizes a motion detection algorithm to detect motion and alerts the user when there is a security breach via SMS or SOUND. A Snapshot and a 10 seconds video recoding of the vicinity is also available after motion has been detected.
