does anyone have a tutorial on how to use Arduino V4 Sensor Shield? Example code?
Assuming you mean....
http://www.emartee.com/product/41798/Arduino-Sensor-Shield-V4.0
... I see very little there that isn't just a matter of giving you easy connections, on a physical level, to the standard Arduino lines.
There's no "programming" as such. Any code that would work for any sensor or output connected directly will be the same as the code for connecting through the shield.
Now this on the basis of 30 seconds looking at the page cited. I won't be offended... delighted, in fact!... if someone can post any improvements to that answer.

Your assessment is correct. The board is just a kind of break out board allowing for different kinds of connectors to be used to access the arduino pins. Servo compatible pin outs allow for the servo to use arduino power (not a very good idea actually as current is a limited resource on a arduino board) and the analog connectors supply +5vdc to power the sensors as well as route the sensor's output to a arduino analog input pin. There is also a 4 pin communications connector that can be setup for serial or I2C with jumper pins. It's a useful board that is used to support the 'brick' line of sensors sold by Asian dealers.
