The Arduino Uno and the MPU that I am using ware opened just 3 days ago. So its can't be that those are not working.
However I have another one, I will try it with that one.
I also do not have access to any other Board, except Beagle Bone Black, which I will work on at a later time. Since I am not currently in a country that has access to dev boards easily, it will take me sometime to get my hands on anything else. I have another Arduino Uno which I can try with, just to be sure.
I will try all the other suggestions as well.
Cheers for the reply.
