10 LED Bargraph

This is a video of the first project I did with my Arduino. It is a simple 10 LED one color bargraph that is driven off of the digital outputs of the Arduino. The code for it is pretty basic, just turning LEDs on and off and then doing a little bit of looping. I added in whatever I thought would look cool. I plan on doing much more exciting things once I get more used to working with the Arduino. The song is titled "Inverting the Tower Temple" and is by GSlicer off OCRemix.org.

@lowIQ04 If you look on the back of the display there should be a little plus sign indicating the anode. But you can also check by turning your multimeter to continuity mode. If you hear a beep then you know that you have the plus side attached to the plus side of your meter.
