Hey guys, I wanted to ask if the sensor shield v4.0 can be used for controlling servo's, DC motors, sensors and other things that could be implemented to build a robot.

And how it exactly works? It covers the whole Arduino body, and how exactly does it increases the current? Is it possible to control servo's and motors with just the Arduino? If not the why? Whats the maximum current an Arduino can handle? How about the Shield?

Where did you get the idea that is does?

Servos - yes. Motors - no.

Because they draw too much current.

In or out? Which Arduino? A typical pin can deliver 40mA of current, although long term safe ratings are lower than that.

In or out? The shield doesn't boost the current of the Arduino, so the same limits apply.
