I have finally began working on my first electronics project this Summer. It all started from a broken Linksys 5 port switch that I got many months ago. After removing the front sticker, I discovered that there was many more holes in the front of the case then the holes that were being used in the working switch. I knew that it would be a perfect case for a LED matrix, so I starting scouring the internet on how to control one (I think this idea is the reason I finally caved in and bought an Arduino). Unfortunately, the holes on the switch are only 3 LEDs high, so I couldn't use it for displaying text like I originally planned. The idea that I came up with was to use the case for a "logarithmic bar graph display." I had a AN6884 chip and perfboard that I purchased from
my favorite electronic component store and I never used. I also had a bag full of 3mm green LEDs that I got from eBay for this project.
