This was a homework code written for my microprocessors class a few days ago. I thought I should post something today since I'm going to be passing out business cards at the Society of Women Engineets conference today and tomorrow so if that's what brought you to my blog, then I'm glad you were curious enough to stop by! Feel free to contact me via email or phone with any questions. My phone number is on my card as well.
