Problem with self balancing robot- wheels only spine one direction

Submitted by Ck101 on Sun, 10/24/2021 - 10:39

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 reading weird letters and symbols when I have the circuit connected. I believe I have added the PID libraries correctly to the Arduino library, as the sketch successfully downloaded to my arduino, but I am not 100% sure. Any help that can be offered would be greatly appreciated. I have posted a link where the code project details, and the circuit diagram can be seen. DIY Self Balancing Robot using Arduino

You need to debug it. Lets start for first step. Rectify the Serial monitor first. How much baud rate are you using?
