Just out of curiosity, how long did your project take to get to the point shown in your video?
I can see a lot of potential with this project and possible expansions
[As a semi side thought, and yes, I'm asking if anyone knows (as well as thinking "out loud"): I wonder how hard it would be to get two Arduinos to communicate via Ethernet/wireless networking to have one as the input module, and the other controlling the Robotic arm..?]
