Re: Python Based Self-Balancing Robot using MPU6050

When implementing a servomotor, which is what a PID loop controlling a motor is, you are wise to avoid using slow decay mode, and ensuring the PWM frequency is high enough. The best set up is to use synchronous rectification (like fast decay except the bridge is always driven, PWM reverses the dire...

Re: Python Based Self-Balancing Robot using MPU6050

Well in GPIO.BCM mode the Pin 19 and 18 have this function . And for 2 Dc motor going back and forth i guess i need 4 pins with hardware (DMA) timed PWM . And the code/library you included is in C any thing i can do with Pythion GPIO library . I am already using Python GPIO.PWM() And any comment on ...

Python Based Self-Balancing Robot using MPU6050

Hello Everybody, I am trying to build a Self-Balancing Robot ( nothing new ) but i am trying to build this Robot with Python Code . I am half way gone , i think . My robot is moving back and forth but it fails to maintain the balance . I am doing some wrong calculation on the PID and Accelerometer A...
