Extreme NXT: Extending the LEGO MINDSTORMS NXT to the Next Level, Second Edition, Edition 2

New input devices—such as keypads, sensors, and even the human body—are covered, along with fun games such as surfing, PONG, and SIMON. On the serious side, there are classic engineering challenges such as controlling an inverted pendulum, making a robot that follows a wall, and building several light-seeking vehicles. Some projects are just entertaining, such as the Etch-A-NXT; others are useful, such as a motorized camera mount that takes panoramic photographs.

This second edition accounts for the important changes found in the next generation NXT, and it also covers the original concepts in greater depth. Details are presented for practically unlimited expansion of the NXT inputs and outputs by using the I2C communications bus, and several power amplifier designs allow the NXT outputs to drive bigger motors. Instructions are also included for adapting LEGO Power Functions motors to work directly with the NXT.
