LEGO Mindstorms is a great tool to gain experience in understanding robotics, but what if you wanted to make your own input sensor? In this guide, we will show how simple it is to construct a circuit to control a Mindstorms robot through GPIO in Raspberry Pi.

We will show every step from connecting the robot to writing the code. The result will be a program in Ch, a superset interpreter of C/C++, to control the direction of the robot with a push-button.

LEGO Mindstorms NXT Tic-Tac-Toe (Naughts & Crosses) Playing Robot was programmed with NXC, using Daniele Benedettelli‘s ‘AI‘ Code. The Robot uses a Hitechnic Colour Sensor to detect the coloured balls placed on the Game Board. The robot’s ability to detect the correct colour of the balls, is far superior when using the Hitechnic Colour Sensor than trying to use the standard LEGO Light Sensor.

Although LEGO MINDSTORMS NXT allows anyone to build complex inventions, there are limits to what you can do with what comes inside the box. This book shows you how to advance the NXT with more than 45 exciting projects that include creating a cool magic wand that writes words in thin air, building a remotely guided vehicle, and constructing sophisticated robots that can sense colour, light, temperature, and more.
All projects are explained with easy-to-follow, step-by-step instructions, so you’ll be able to create them successfully whether you’re a novice or an expert. This book also shows you how to expand the programming software and use the alternative language NXC.
