Maxbotix (with Arduino) LV EZ1 questions


I am having problems with wrong readings from EZ1 and my Arduino. I am using the PWM mode and I have checked all tutorials/samples I found. So my questions would be:

Using itg-3200 gyro to measure angular position

Hi all,

I have the sparkfun itg-3200 gyro connected to an arduino Uno. The example code works but it only indicates angular velocity.

Can this be used to measure angular position? Or do I need to throw in a accelerometer as well?

This gyro is supposed to be integrated with a pan-tilt servo kit, thus relaying it's orientation back to the uno.

Adafruit motor shield, just running one motor

I have looked at the tutorials from adafruit, such as this one:  http://www.ladyada.net/make/mshield/use.html and I can include the library in my program, I tried the examples and I get nothing. I am using 7.2 volts for my power supply and the motor is from an rc car. I have tested the motors with a different h-bridge that came with my DFrobotshop rover and it works fine.

Is the POP-BOT arduino microchip compatible with the BOE-BOT developer board?

I have an Inex POP-BOT which came with an arduino-like microchip, and was thinking of getting a BOE-BOT, which uses a Board of Education with a BASIC stamp microchip attached to it. Now my question is, there two chips seem to look identical in size, and can both be detached from their respective developer boards, so what I'm wondering is, would they be interchangeable?

easiest motorshield to program?

I have a adafruit motorcontroller. I thought it was easy to program but, looking at some of the code that others have written it seems really complicated. Please tell me that it just looks hard and is really to program. Also, how do you get librarys thing to work? They have a tutorial but my computer looks different than their photos. If you know of a motorshield that is REALLY easy to program please tell me. Thanks for the help!
