Using Servos for Measured Movement

Now that we've looked at motors, let's look at a more precise way to add to movement to our projects: the servo. We'll dive into how to wire up one servo, then another, and how to code both a single servo and multiple ones. 

The following topics will be covered in this chapter:

• Differences between motors and servos
• Getting a servo working with Johnny-Five
• Project – two servos and the REPL
• Project – the continuous servo
