This is the long overdue update of the house project conceptualized a while back with my kids. In this project, a model house was wired for simple lighting using LED's.
|The USB home|
Each part or room in the model house will be lit by a dedicated LED and each LED will be directly connected to the pins of the microcontroller, in this case, the Arduino Uno.

|The Arduino being wired|
|The GUI in a Windows PC|
|The GUI showing the check boxes and sliders as control inputs|
The model home is connected to the PC via the USB port. The Uno will function as a slave unit with the PC as the master. If a user clicks on the GUI, the corresponding LED will light up (or toggle off) in the actual model home. This therefore illustrates how a real USB controlled home can be made possible.
