Anyone here have experience with Arduinos? Whats the coolest thing you've made with a duino? I just ordered one since I want to learn a bit of coding, the most I've dealt with in terms of coding is matLAB which I learned in a class, but I have no experience with C/C++. I also have a 3d printer on the way, so I cant wait to use that together with any robotics ideas I have. If anyone wants to post pictures or videos feel free.
