# Can I use tinkerkit hall sensor as compass

I'm using Tinkerkit shield in combination with an Arduino standard board. I need a simple compass sensor in order to determine the direction (I don't need a great precision), unluckily similar sensor that works "out of the box" with Tinkerkit does not exist. Can I use the standard Tinkerkit hall sensor (http://www.tinkerkit.com/hall/) as a compass? If not, can you suggest me how to connect a standard Arduino compass in Tinkerkit?

UPDATE

The hall sensor does not work

Of the 3 pins on it, the - pin goes to the GND pin of your Arduino, the + pin goes to the 5V pin, and the pin in the middle can be connected to any of the analog input pins of the Arduino, say A0. Jumper wires can be used to connect these up.
Note that this is not going to be very precise, but for an experiment it should serve the purpose. Also, the variation from the middle value will probably be very small, as the hall sensor IC used is not a very sensitive one: 1.3 mV/Gauss.
