MPU6050 / OLED not detected on ESP32-C3

Hi everyone,

I’m currently working on a project: a smart wearable bracelet that detects impacts using an MPU6050 and sends alerts.( just student work not have to do with money or big things) just learn becus I am a beginner no need to drama

I’m using these components:

  • ESP32-C3 board
  • MPU6050 sensor (address 0x68 or 0x69)
  • OLED display (address 0x3C or 0x3D)
  • Buzzer (optional)

The problem is: I don’t know exactly what is wrong.
The device doesn’t respond. I’m not sure if the board is broken, if my wiring is wrong, or if something is missing.
These are the only parts I have, and I’m in a hurry because I need to finish this project very soon.

Any advice would be greatly appreciated.

That's why you didn't read the forum guide and posted in a forum category where it clearly says "do not post here"?

I will move your topic for you.

How do you think we can help you? We have nothing to work with, it's like telling you I lost a diamond ring in the Atlantic ocean somewhere, can you find it for me?

Which device exactly is not responding?

One thing that you can do to narrow down the problem is to download an I2C scanner sketch and see if it finds your display at one of the addresses that you have mentioned.

no broooo im in grade 10 and it's just small project i didn't want a score or degree anything I just need to know like I just need some advice, I’m not looking for an argument. If you can’t help, that’s fine.”

thank you very much

A lot of the old farts that answer questions here have no idea what grad 10 means other than it is suppose to indicate your age. But as the grading system changes from country to country we can't look it up. So how old are you?

No-one can right now. You are young and probably still think adults have some kind of problem-solving super-power. They don't. They need relevant details and lots of them.

If you read that forum guide (sticky post at the top of almost all forum categories) that will lay out for you what you need to give to enable the forum to help you.

It's inevitable that with a rating like that, you have a treasured crystal ball that knows all the answers ;-)

Here are some things to try:

  • Upload & run the i2c scanner sketch from the examples menu in the IDE. If you can upload and run them, then your board is probably ok. If you can see two devices on the bus, you will know what addresses they have. If you can't see both, try connecting them each in turn.
  • Upload & run one of the example sketches for the display, then one of the example sketches for the sensor.

These steps will tell you if your display or sensor is working or not.

I truly appreciate your kindness and willingness to help. Unfortunately, I’ve decided to let go of this project for now.

Thanks for letting us know about that. We can now add you to our ignore lists so that we can avoid wasting our time helping you in future.

I understand. I’ve decided to stop this project for now because the deadline is here, but I definitely plan to continue it in the future since it’s a year-long project.
