A maze-solving simulation with an integrated database system. (ReactJS, ExpressJS, MongoDB, NodeJS)

Demos:

• 
• 
• 
• 
• 

• Implemented web app GUI (ReactJS) that simulates the maze-solving procedure of Dijkstra and DFS algorithms.
• Implemented a queue and stack data structures for the array to support backtracking and tracing of the algorithms.
• Integrated a randomized maze-generating algorithm using BFS with flexible sizes on a Dynamic 2D array.
• Deployed MongoDB cloud database, ExpressJS’s back-end Render server, and ReactJS’s front-end GitHub server.
• Designed REST apis for communication between the GUI and the servers for database modification.

Race car

A GUI that transfers computer input to motor input via wifi. (Python, Pygame, Socket, Adafruit, BeagleBone Black)

Demos:

• 
• 

• Implemented a GUI to track keyboard inputs and report the car’s motor speed, and turn angles using Pygame.
• Integrated and designed a responsive system to control the car via Wifi using Pygame and Socket.
• Converted hardware values and human metrics for GUI readability and hardware controlling.

Task controller

Controlling process execution of a simulated OS environment.(C, low-level programming).

Demos:

• 
• 
• 

• Implemented and synchronized multiple queues to store process data using a linked list structure.
• Transferred user inputs to process signals and guaranteed the delivery of signals to processes.
• Synchronized signal communication between processes and queues to avoid race conditions.
