What devices are turned on at any given time depends largely on which of us is here, and what we’re doing.
This project is a system to reduce our power consumption, particularly when we’re not there.
The book assumes that you have some experience with Arduino and micro-controllers (i.e., do you know what a breadboard, jumper wires, and circuits are? We start with a very brief introduction to RFID, follow up with two introductory technical tutorials on Arduino, and end with a fairly simple home automation project: Between my officemate and me, we have dozens of devices drawing power in our office: two laptops, two monitors, four or five lamps, a few hard drives, a soldering iron, Ethernet hubs, speakers, and so forth.
Even when we’re not here, the room is drawing a lot of power.
Disclaimer: I received this book for free through the O’Reilly Blogger program. When you see “I am a sentence I am another sentence,” you know that you’re really looking at two different sentences even though the period between “sentence” and “I” is missing.
If you try something similar with the computer (try leaving the semi-colon off in C or miss an indent in Python, for example), you’ll get a nasty error message.
The authors go on to talk about setting up an annotation project: determining your goal, creating your model/specification, and creating/storing your annotations in a flexible but easy to create (by annotators) manner. I had no previous experience in this area, but I had no trouble understanding the subject matter for the most part.
