In this article we’ll build an XML-driven video gallery exploring a lot of new Flex 4 features (out in spring 2010): skinning spark components, spark containers, new states and transitions; but we’ll also use some “old” concepts like itemRenderers, custom events dispatch, load data from an xml file (using the Singleton design pattern), value objects, embedding fonts, css and a lot of other useful stuff when you develop Flex applications.

The Wii nunchuck controller contains a 3 axis accelerometer, one joystick and 2 buttons for only 20 euro and you can easly use it to manage your Arduino applications.
In this article we’ll see how to move two servo motors using this controller (providing two videos, prototype images and complete source code)

With Arduino you can build a lot of cool projects regarding domotics and robotics and manage servo motors is one of the most important stuff to enter in the home automation world.
As we saw in previous articles we can move and manage servos using your own microcontroller but naturally they have a limited number of analog pins.
So, what’s a servo controller? It’s another board that extends your microcontroller with new servo dedicated ports. In this article we’ll see the power of the Micro Serial 8 Servo Controller Kit applied …
