The two project parts are closely related, and both involve the control of IO pins: one uses an external board that provides eight additional GPIO pins, and the other is based on the RasPi itself.
The external board uses the 1-Wire protocol that was introduced in the Chap. 10 project for building a weather station. This board may be either controlled through a program running on the RasPi or accessed using the home network, as was demonstrated in the Chap. 10 weather project.
The other project part directly controls the RasPi GPIO pins. This part may be thought of as ...
