Summary

In Chapter 9, you worked your way through three very simple projects that show how easily servos can be controlled using the servo.h library. You can easily modify these projects to add up to 12 servos to make a toy dinosaur, for example, move around in a realistic manner.

Servos are great for making your own RC vehicle or for controlling a robot. Furthermore, as seen in Figure 9-9, you can make a pan/tilt rig for camera control. A third servo could even be used to push the shutter button on the camera.
