Summary

In this chapter, you have put control over (a small part of) the world in the hands of your Arduinos. Using your self-built wireless relay, or an off-the-shelf wireless power socket, you have enabled your network to switch things on and off. To keep ultimate control in your own hands, you have added control over the intended temperature to your Beebotte dashboard as well.

These examples should provide a good basis for more complex projects, where the network has more fine-grained control over things than just switching them on or off. Anything you can let your Arduino control (and there are plenty of good tutorials and libraries out there), can be done wirelessly using the same approach used here. Similarly, you could be using physical buttons, knobs, and displays instead of, or in addition to, the Beebotte interface for providing setpoint control, or any other kind of control for that matter.

In the next chapter, you will be looking at using XBee modules without an Arduino or other...
