Make a Mind Controlled Arduino Robot shows you how to build your own. You learn to measure attention level with a NeuroSky headband and send this information into Arduino. You will also build a line-avoiding system into the bot. And, of course, you will build the chassis of your robot from scratch.
If you incorporate Arduino or Raspberry Pi into your project, you can build much more sophisticated projects that can react in interesting ways and even connect to the Internet. This book starts by teaching you the basic electronic circuits to read and react to a sensor.
Make: Sensors is the definitive introduction and guide to the sometimes-tricky world of using sensors to monitor the physical world. With dozens of projects and experiments for you to build, this book shows you how to build sensor projects with both Arduino and Raspberry Pi
