Drifting on MPU6050 #9

Hello, great job, works nice. sorry if my issue is unrelated but I am trying to make a self-balancing robot and I am getting drifting on gyro angle like it is initially 0.01 degree and after a couple back and forth movements the gyro angle becomes 0.20 in stationary position.. is this fixable or totally my own issue?

thank you for your time!

note: in README.md exaple codes, the #include does not include .h so I got issues while uploading. if you can change them to #include would be better :)

Hi! Yea, drift is a common problem with accelerometers and gyroscopes. What you can do to minimise it is to:

calibrate the accelerometer and gyroscope
change the sensitivity settings to be less sensitive
write an algorithm to return the average or median of the gyro readings and implement your own mpu6050.update()

I hope these tips help!

(Btw there might be a better equipt library for the mpu6050. I myself am working on one, but its still under development (it has methods, like getAccelXMedian()...)

Did anyone find a solution for this?

I keep on getting drift and makes it quite unusable.

Some axis increase gyro angle by almost 1 angle per second :/
