Chapter 9. Even More Useful Sensors
Your projects may want to do more than just avoiding barriers. In this chapter, we'll go
through the following topics:
• How to add a digital compass so that your projects can sense direction.
• How to add an accelerometer/gyro to your project so that you can sense the tilt and
movement of your projects.
• How to add an altimeter/pressure sensor to your project so that you can sense your
altitude. These can also be useful in weather prediction.
