Arduino MKR1000 skateboard

I am big fan of the longboard pseudo sport, but one of the probles has always been, how to break the board when the speed is too high, you could slide the board but that could literally throw you several meters in the air, that's why I decided to create this rear break for my longboard using an arduino MKR100.

I used two servos for the rear wheels, with 3d printed supports I could be able to avoid the wheels to continue running.
