Gameduino: “a game adapter for microcontrollers.” I’m interested in the sensors you can easily connect to the gameplay using Arduino, effectively rendering the old school-feel of the games produced from Gameduino into a fresh experience. Here’s another one related to gaming.
LCD Shield Kit: a space efficient LCD screen, taking up only a few pins as opposed to previous models. I like screen inputs that look very “digital” so I’m biased. I could see microcontroller easily asking for user inputs with this.
EasyVR shield: “a multi-purpose speech recognition module designed to add versatile, robust and cost effective speech and voice recognition capabilities to virtually any application.” Combine this with the previous two shields, and we’ve already got some interesting things going on. (Voice recognition as part of a multiplayer game mechanic?)
