HI, sorry for my english. 
This is my first topic in this page, and I want to begin sharing a project i made. It is about a robotic arm of 3 +1 DOF that plays against a human the ancient and famous gme tic tac toe. It is controlled by arduino One for moving the servos and a program in visual basic .net that contains the logic of the game.
I hope you like it, and so, please like the video in youtube. Thanks.
