Chapter 10. Going Truly Mobile – the Remote Control of Your Robot
Now that your robot is mobile and has several ways of sensing the outside world, you'll want to disconnect it from the tether cable that you have been using to communicate with it. In this chapter, you'll learn how to communicate wirelessly with your robot. Depending on your choice of method, you'll be able to communicate across the room or across a distance of up to a mile. Specifically, we'll cover the following topics:
Connecting Arduino to a simple radio frequency (RF) transmitter/receiver pair
Connecting Arduino to an XBee transmitter/receiver pair
Connecting Arduino to a Bluetooth transmitter/receiver pair
Connecting Arduino to a Wi-Fi network using a Wi-Fi shield
As your Arduino will now be remote, you'll need to power it with an external source. Your Arduino will need at least 250 mA, but you might want to consider providing 500 mA to 1 A based on your project. To supply this from a battery, you can use one of several...
