I'm curious to know why you don't just run them straight off the Arduino? What does the controller bring to the party?
Hello, everyone.A month ago I bought a PCA9685 16 channel 12-Bit PWM driver for controlling my servos. I have 4 HSR-2645CRH Hitec continuous servos. I am trying to control them using the PCA9685 driver but I'm having problems with the code. Can anyone help me with it, I can't make the servos move in one direction or another and I can't control their speed.
What does the controller bring to the party?
They work terrific and are available for very cheap. I used to run into problems with jittery servos that would move slightly when they were supposed to be standing still. Some brands of servos worse than others, but all seem to run into this problem with certain libraries combined with servo control. That makes a shaky robot arm or difficult to view video. Switched to a PCA9685 and haven't looked back. Rock steady when they hold a position.
