Colour Selector from UCIT course

Here are some details of the colour selector made by Jaakko Hakulinen.

The application maps data from accelerometer to colour and uses LEDs to display this colour. The x-y axis data is converted into polar coordinates and angle is then used as hue and distance as colour intensity. Brightness is always maximum. This HSB value is then converted to RGB values. In addition, touch sensor is used to switch between reading the accelerometer data and controlling the LEDs using PWM.

The system runs entirely on BS2. It does send some debug output, which can be read on PC side.
