2. 2 Objectives At the end of this exercise, you will be able to:

3. 3 Demonstrate that an IR motion detector can be used to trigger a macro. Demonstrate that an IR remote control unit can be used to trigger a macro. Demonstrate that a light sensor can be used to trigger a macro.

4. 4 Demonstrate how macros and timers can be sequenced together to form complex scenes and scenarios. Demonstrate that one macro can call another macro. Demonstrate how a program loop can be used to repeat a sequence of events.

5. 5 About This Presentation You have been learning about home automation and how to accomplish it. But now we need to side-step a moment and think about energy sources. Residential automation depends on electricity. But where does electricity come from?

6. 6 What about alternate power sources? What about connecting to the grid? Power your home two ways, the grid and alternate power. This can be a challenging part of home automation.

24. 24 The Power Grid Power company’s generators, cables, poles, transformers, etc. Delivers electricity to our homes and businesses.

25. 25 Your Options Connect to the grid. Generate your own electricity. Generate your own electricity and connect to the grid too.
