Arduino digital compassing

Arduino polishes up its navigation skills via an inexpensive compass sensore component –

A small digital compass based on hall effect is connected to an Arduino 10000 board. The logic in the board turns on and off leds depending on direction. There are 4 leds, one for each in N,S,W,E. When two leds are ON the direction is in the middle (es. NW). The digital compass chip (the white cylinder) comes from http://www.dinsmoresensors.com/ and costs 10$
