Never mind, guys. Got it working. I hadn't noticed the define statements were commented, i had to uncomment them to get the readings. But I haven't got the teapot application working though It just doesn't move. If anyone does get it, Please help me out.

Sorry, for using your thread. I happened to have your same problem. Like Krodal said, i connected INT of my MPU-6050 to digital pin 2 of the arduino, still the serial monitor displays junk values. Any idea what i should do?

Actually, that's the same document. Well if you do try it, please let me know.

Yep got it. installed it.as told in              https://docs.google.com/viewer?a=v&q=cache:wGOxZcVHj58J:invensense.com/mems/gyro/documents/AN-MPU-9150IMF%2520InvenSense%2520MotionFit%2520SDK%2520Quick%2520Start%2520Guide.pdf+&hl=en&gl=in&pid=bl&srcid=ADGEESherjc2YJZQFLGmgss8FyOOLPoaW54oy0MKNtOgtBg9Hv0uEqDKW6dwtYOnUBWwMtd3Q93DTOCnTMWioGhLtTr3bdSKj0j1IksdsAqIcoQhmNT4ozaLJLiFwZdX6Li5bgDa6Dnd&sig=AHIEtbR9iVy9UWZJyH1_BBo4sL_BmzkpTw               , page 8 Created a shortcut and added COM4 to the target, but it still says "unable to open port", when clicked. The arduino is connected to COM4, checked via serial monitor, working perfectly. Any suggestions?

Sorry for the late reply.
 @krodal  As a matter of fact, i did try your code and it worked perfect. Now i wanted to have some visual feedback, so decided to look ways on simulating it.

@freak174 i registered in invensense, but still was not able to download their teapot software zip. It's not freeware? I did try downloading it from another site, but it returned an error during installation. The code seems to be fine. I also added the MPU6050 and the i2cdev library files.. Is there any other place where i can get my hands on the teapot software?


Thanks

The project you linked to is a perfect example.  What does it matter if the phones allow you to control the robot from miles away if you have no means of feedback once it's out of your sight.  How do you control something if you don't know where it is and what's around it?

If the phone in the robot has a camera, you could place a video call to the phone, so you'll be getting a visual feedback. So I'm pretty sure you control it miles away, provided, there is cell phone coverage.

You would need a dtmf decoder ic. It actually converts the different frequencies that is produced in the key strokes to a digital signal. You could use these digital signals as input to your microcontroller. Connect your dtmf ic to the mobile in your robot, take the digital outs from the dtmf ic to the arduino.

Hey.

Is there any way i could simulate my MPU-6050, using the teapot or MWC software, I've been searching for the correct arduino sketch plus the correct version of the software, I have a feeling that my simulation is not working because i'm getting those two wrong. Could anyone give me correct links? I'm using arduino version 1.0.1.

Thanks

The sketch compiles for a Duemilanove (both ATmega328 and ATmega168), but you have to update to the new Arduino 1.0.1 !

Oh okay.

I tried the i2c scanner and it was working fine.

As you told, i changed the f from the serialprint, but now a new error comes in this code.

Code:

  n = Wire.write(start);

error-

class Twowire has no member named write

Thanks for your reply.

I haven't changed any of the code, copy pasted the entire code. I'm using arduino 0022. Board- arduino duemilanove.

I recently purchased the MPU-6050 from ebay. I've always been skeptical about buying from ebay, and luckily they have a 14 day return policy, if it is damaged. So, i need to check its working asap. As i'm new to interfacing with i2c, i thought for the time being i'd use this code from http://arduino.cc/playground/Main/MPU-6050 to check if my component works. But it shows compile error "F was not declared in scope" (  Serial.println(F("InvenSense MPU-6050")); ) Could someone help me out? Thanks in advance.

@james you were probably right, the arduino actually works now. Thanks a lot for replying to this post.

Disconnect everything from the board and see if starts to function again.  If so, it helps to indicates a short circuit.

Nope, it isnt working.
