hi
im doing an autonomous robot project now
i need a compass to direct my robot.
is there any electrical compass that give us analog output (in terms of how many degrees south or something like that) ?
so i can direct my robot precisely.
thanks

Nope-modern compasses today are all digital. Hmc6352 is common and uses i2c
-
CPMS03 is also digital, and it's very easy to use, It can be controlled through I2C or PWM

Hi,

Usually, the analog types are (like this one (http://www.imagesco.com/articles/1525/01.html)) of the sine/cosine output type.

but for digital how can we determine the exact direction (like the degree)?
from what i know the digital compass will only give value 1 or 0 whenever it face either S, N, W, or E.

I mean digital communication-for example, the hmc6352 uses the I2C protocol to communicate with a host microcontroller
