Lose Yourself in the LED Timer Game with FPGA


Hey FPGA lovers! If you have ever been a fan of arcade games, here is a chance for you to re live the glory days! The LED timer game with FPGA consists of an LED-button interfacing with FPGA. The project is really simple to implement and it is a great first project for FPGA aspirants. The game is similar to the moving light arcade game, where you press a button when a particular color LED glows. As you progress the game gets faster and harder!

The hardware requirements for the project are a FPGA board, Male to Male jumpers, 10 LEDs (9 of which are the same color) and breadboards. The project has been coded by the author for a 10 LED version. The wiring details are given in step 7. However you can extend this to any number of LEDs once you go through the code.

Though any board can be used for this project, the author has shared VHDL codes for Nexys 3. So here you have a good challenge adapting the given code to your FPGA. Another interesting aspect is that you may need to adapt the implementation of the button that is required for the game. So the hardware interfacing not only involves connecting LEDs to FPGA, but thinking a bit outside of the box to get around this minor drawback.

The pieces of software required for this project are Xilinx and Adept. The code has been broken into modules and explained well in step 5. The code consists of a number of modules in VHDL (.vhd) that consists of using the primary button for playing, Display for keeping score and LEDs for driving the game.

The author has done a great job in providing clear instructions and the codes have been written following simple logic. Another major factor is the flexibility in scale of the project where you can implement this game to cover 10 LEDs or even 100s of them. Game on!
