406 COMMON ELECTRONIC COMPONENTS FOR ROBOTICS

Speakers, to better hear your robot.
Microphones, to better your robot’s hearing you (is that even a proper sentence?). See
Chapter 46, “Making and Listening to Sound,” for more on speakers and microphones.
Light- sensitive resistors, transistors, and diodes, to give your robot the gift of simple sight.
These components are detailed more fully in Chapter 44, “Robotic Eyes.”
LCD displays, to let your robot communicate with you in words. Read more about how to
use these in Chapter 47, “Interacting with Your Creation.”

On the Web: Stocking Up on Parts

So what parts should you get for your robotics lab? How many resistors, and what values,
should you stock up on? That can be a tough question if you’re just starting out. The details
would kill too many trees, so as a bonus to the readers of this book, I’ve outlined some sug-
gestions (with suppliers and parts numbers) on the RBB Online Support site, described in
Appendix A.
