electronic compass
« on: May 23, 2010, 09:56:38 AM »
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,

is there any electrical compass that give us analog output (in terms of how many degrees south or something like that) ?

Usually, the analog types are (like this one) of the sine/cosine output type.

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?

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
