I'm creating an Hexapod using a Raspberry Pi 3, 2 X 16 Channel Adafruit PCA9685 servo controller chained, and multiple Tower Pro MG995 servos for the limbs.
Issue that I've encountered is that when connecting multiple Servos to the controller and then to the power supply, most of the servos start to move on their own without me running any code or commands.
This issue does not occur when I test individual servos or at most 3 at the same time.
I'm currently using a 5V 2.5A power supply and have tested a set of 4 AA battery pack 1.5V alkaline with a similar result.
As a guideline I'm following this template.
