For a project in school I have to build a robot playing a bass guitar.
To play the notes I planned to plug 16 servos to Adafruit's PCA9685 but it doesn't supply enough Amps to the servos. How can I power the servo motors externelly but still controll them via the PCA9685? I know that I don't have enough amps because the PCA9685 is able to controll much weaker servos, but these aren't powerful enough. Can anyone help?
I use the Raspberry Pi 3 model B+ to control everything and several BMS-410C as my servo motors.
