Controlling the steering servo with a mouse

Instead of using a potentiometer to control a servo, i will use in this case a mouse.

In order to send a value to the Arduino, depending of the mouse movements, I have to make a short program which will run on the computer side.

To create this program, I will use a development platform called Processing. It is Open Source, easy to use, and specially made for interaction and animation. Actually, the programm Arduino is based on Processing.

For more info: http://processing.org/

So, I will have on code, running on Processing, sending the value to the Arduino, depending of the mouse position, and another code, running on the Arduino, to control the servo depending of the value received through the serial port.

I wil use:

- My computer (and the mouse)

- The Arduino

- The USB cable and some simple wires

- The steering servo of the Kyosho car

As we do not use any potentiometer anymore, the servo will be directly connecter to the Arduino. +5v pin to the red wire, GND to the black wire (here brown), and the pin to the white wire (here orange).
