Hello everyone, I have finished building the circuit for my self balancing robot, yet it is not working as intended. After connecting the power source, the dc motor wheels spin at a constant speed and only in one direction, regardless of how the MPU6050 is tilted. My serial monitor has also been re…

One thing I can suggest is to initialize the motor control pins at the TOP of setup() rather than at the bottom. That way, if the initialization of the MPU6050 gets stuck you will at least have the motors turned off.

Hi, @cmantheballer Welcome to the forum. Please read the post at the start of any forum , entitled "How to use this Forum". [image] How to get the best out of this forum IDE 1.x See also FAQ - Arduino Forum for general rules on forum behaviour and etiquette. Hello, Wel…

[image] cmantheballer: After connecting the power source, the dc motor wheels spin at a constant speed and only in one direction, regardless of how the MPU6050 is tilted. Sounds like a wiring error. Check every wire.

Yes, I doubled checked to ensure I was set to the correct baud rate but still was receiving these symbols. I believe the issue stems at the arduino/code, as when i detach the power only supplying the arduino, the wheels do not spin at all. I have built many arduino projects in the past but this woul…

Hi, Please read the instructions posted in post #4 on how to post your code. Thanks.. Tom... :grinning: :+1: :coffee: :australia:

I have checked the wiring for my project to ensure there were no faulty connections, yet the wheels still spin at a constant rate in one direction.

Unfortunately I have checked this issue to no prevail :frowning:

Here is also a picture of the output I am receiving from the serial monitor: [Screenshot 2021-10-24 10.50.00 AM]

Looks like a baudrate mismatch. Does your sketch have Serial.begin(115200);?

Hi,
You need to write some code of your own to test the motor drive hardware.

Can you please post the self balancing code that you are using now?
