First time using a Arduino and it's for a school project. I have a uno starter kit (but willing to upgrade) and for my project I want to make something VERY similar to the arduino laser harp video that is floating around. However, I really have no idea where to begin. Such as a decent website that I can purchase items from that is trustworthy and in the US.
I have little knowledge of C+ but am willing to make this happen. I guess what I'm looking for is how complex this is going to be and what price range im looking at?

Edit: Thanks for any help in advance.
