traffic-light-controller-using-FSM

This project designs and simulates a Traffic Light Controller using VHDL and FSM architecture. The system controls traffic flow between two roads through sequential state transitions driven by a clock signal. Vivado simulation verifies correct operation, demonstrating digital logic, FSM design, and VHDL coding.

Bubbles

Bubbles the simple, easy to use HTTP web server that is browser controlled, and capable of serving static files over the internet, either streamed from disk, or direct from RAM without lag. A GUI administration panel is accessed through your web browser (e.g. "http://localhost:1080/admin/" + default password of "admin"), which controls all her settings and vital functions, all in real time. Apart from serving files, she is capable of tracking site visits (site counters), receiving emails, accepting contact form submissions with support for Spam Guard, and recording site activity as date stamped traffic logs. She also includes a built-in log analyser for making sense of her traffic logs. These and other features make her more than capable of running multiple websites with little to no headache. Her design is light and stable, and an extensive block-based memory management system ensures all her key operations use memory in a sustained and reliable manner.

OpenSIMPLY

OpenSIMPLY is an open source project for simulation modeling in Delphi, Lazarus, Free Pascal. Download OpenSIMPLY at opensimply.org The project is free computer simulation software based on discrete-event approach. OpenSIMPLY is a science software with very high simulation performance. So, the simulation results can be obtained much faster. The project is suitable for people with any modeling experience, and can be used for both science and education. Some application of this modeling software are: - traffic simulation - network simulation, - emergency and evacuation ways simulation and much more. This simulation tool runs in Windows and Linux, on 32-bit and 64-bit platforms, as a GUI or console (terminal) application. Write the model only once, simulate anywhere.
