i`m using arduino nano.

thanks for help me...

How to get a degree value of Accelerometer MMA7455?

help me please...

Do you mean using the Arduino IDE? If you do, then I can't see how. The CMUCam4 has a Parallax Propeller processor.

but it`s shield compatible with arduino (duemilanove & UNO).

have someone programmed CMUcam4 Using Arduino ?

Sharing please...

what is function of z-axis in accelerometer?

i want an accelerometer like MMA3201, but it has 3 axis.
this datasheet of MMA3201

i want to buy a accelerometer that can be work in high G (about up to 20G). what kind of accelerometer it this??

can i setting the resolution of cmucam3???
i want to set the resolution about 200x200 pixels.
thanks before...

where can i download datasheet of nunchuck 3L02AE?
thanks.. to help me.
 

You cant, because when you tilt more than 90 degrees you are in fact inversing the chip, so your gravity values become negative, so it becomes the same tilt, but you just have the board/acc inverted.

so what can i do to measure it become 360 degrees?
is this accelerometer only measure 90 degrees?
 

i have read the code from this site
http://rubenlaguna.com/wp/2008/11/03/arduino-tilt-sensor-using-mma7260q/
but it just 90 degrees, can i measure the tilt until 360 degrees??
I use arduino mega 2560.
 

how to calibrate tilt accelerometer mma7260q???
