Okay, then you'll need to post or upload what source code you currently have written, along with the very least a screen shot of the simulation design or more beneficial upload your simulation files.
If you are in need of inspiration, you also may want to search for similar projects already posted in this forum, as I know there have been several posted in the past.
We would be happy to offer advice and troubleshoot any issues you are currently experiencing, however it's doubtful anyone will post a ready made design and source code.
