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 …

We’ll use the Arduino microcontroller and an analog joystick to control two servos: the first one will be connected to the horizontal axis, and the second one to the vertical axis.
We also use a the Lynx B-Pan Tilt Kit (BPT-KT) to connect servos together. Check the video and imagine what kind of robots or cool stuff you could create using more devices and a lot of pacience ; )

In this article we’ll control a servo motor using a joystick and the microcontroller Arduino.
We’ll also set the value of a LED-2-colors in according with the stick axis.
It’s just an introduction for the next article: Arduino and Flex: connect a joystick to your application
