MPU-6050 Accelerometer Values Stuck

gigahertz-t · November 25, 2025, 11:50pm

Hello again!

I was coding a MPU-6050 accelerometer to use on a personal project, and I was moving it back and forth to see if it worked. The code prints the accelerometer’s values to the serial monitor, but I noticed that after a few seconds, the accelerometer values get “stuck” on the same value even if I move the sensor around. (The x acceleration likes to get stuck on 2.45 and the y acceleration likes to get stuck on 0.00.) Do you guys know why this happens? Thank you!

Here's a video of the serial output:

Copy and paste in code tags the serial output, videos aren't that useful.

Sounds like intermittent wiring. Please post a focused, close up photo showing all the connections.

Sorry about that. The "acceleration X{insert number}" and "acceleration Y{insert number}" are what the accelerometer records. The positions are just the double integral of that.

Here you go

Here's the schematic from the tutorial I used with the same wiring:

van_der_decken · November 26, 2025, 2:51am

I hope that header is soldered to the PCB. If not, there's one of your problems.

gigahertz-t · November 26, 2025, 3:06am

It is. Wasn't my best soldering job but it's on there

van_der_decken · November 26, 2025, 3:10am

Whew! You'd be amazed/appalled at how many folk think just sticking the pins through the holes will magically work, so it's the first thing I ask when it's not apparent.

sonofcy · November 26, 2025, 3:20am

I think you need to re-flow the 1st 3 pins.

sonofcy · November 26, 2025, 3:21am

Set iron to 700F/370C

If you don't "move the sensor around", does it still get stuck? If not, continue to suspect loose connection(s).

By the way, the sensor is a 3.3V only part, and bidirectional logic level shifters are required on the I/O connections for reliable data transfer to a 5V Arduino.

There are plenty of bad tutorials that suggest otherwise, and are best ignored.

gigahertz-t · November 26, 2025, 8:45pm

Re-flowed the first four ports, and swapped out the wires.
It works perfectly fine now... probably due to a bad vcc connection.
Thank you!

Oh really? Thanks for correcting that! I will make sure it's plugged into the 3.3v port.

van_der_decken · November 26, 2025, 9:07pm

No, the sensor has a 3.3V regulator on it so 5V is correct, it's the signal levels that are 3.3V and should be converted.

You got away with it in this case because I2C is open drain, the sensor board has pullups to 3.3V and the R4 doesn't have strong pullups to 5V (just its weak internal pullups). A level converter like @jremington suggested is still a Really Good Idea.
