Afterthoughts

After completing this project, there are a few things we could have done differently. First, we could have used an external source of RAM to store a larger database so that our map could have been more detailed. Second, we could have used a larger LCD for displaying our output. The one we used was satisfactory, but was lacking due to the 20-character per line limit. In retrospect, we would try to use a pixilated display that could not only display text, but maps as well. Third, we would try to make our device completely portable and powered by battery. This would allow the device to be used in automobiles, increasing its usability.
