Here’s an Arduino with a shitload of modules and shields attached to it. Blogger Matt sells these on his site, Liquidware.com, for $249.93. It comes with an Arduino, a MeCap Backpack, a TouchShield Stealth, an ExtenderShield and an InputShield.
The TouchShield reads the position of the joystick, and outputs a little colored dot on the TouchShield screen. It’s essentially an open source portable gaming system. With the appropriate programming, you’ll be playing Missile Command in no time. Hit the jump to check out the vid.
