zardOz2 - Custom level - from AndroidzardOz's Principia Tutorials #15

Need help? This example shows the basic function of the Velocity Meter, Sincos and Atan2.

The Velocity Meter is used to transmit speed and angle coordinates to other objects.

The Sincos takes an angle signal and splits it into four graph coordinate signals +Y/+X/-Y/-X, the Atan2 takes four coordinate inputs and turns them into an angle signal. (See tutorial #12)

This gives a smoother movement with ~ 250° rotation but CCW. My truck speedo rotates C.W. so an inverter after the mov. avg. to get the CW should work. :)
