[NanoChip] Electronic controller for easy braking & controlling without hw brakes

Controls
Left-Right: Arrows
Handbrake: Slider
Brake: F

Do you know the problem with the ugly linear motor brake? Here's the solution!
This electronic chip stops the wheels so they can't go on rolling. Notice: this is a smaller version of another level ( http://principiagame.com/level/5414 ) check it out to see how that works and for the speed control function. Feel free to use it in your vehicles, would be cool if you post some nice cars as derivates. I hope you like it and it helps someone!! :)
Update:
Made it pretty small!
