Arduino Robot Shield v2.1
thingiverse
To quickly attach sensors and motors to an Arduino for prototyping simple robots, I've created a prototype board. Tested with sumobots and a fire-fighting robot, the board offers improvements over Ladyada's motor shield. Future iterations may include a NAND gate for extra digital lines, a mini prototyping area, and removal of built-in potentiometer and speaker. Suggestions welcome. The ultimate goal is to sell kits through Tufts Robotics Club (http://tuftsroboticsclub.com) to aid robotics enthusiasts. Contact langfordw[at]gmail[dot]com for inquiries or potential purchases of extra boards.
