What's wrong with my code?
Hello everyone,
I was just wondering why this piece of code is not working.
The code get uploaded normally to arduino
But when I move the gyroscope it just give me random values of X & Y & Z
Im expecting 0,0, variable...
I checked the connection and it was correct
I thought either the sensor is broken or the code is wrong,
I'm using it to measure the acceleration of a moving object
Any ideas??
