Hi All, I've connected a servo to adafruit's 16-channel servo driver (PCA9685) on pin 0. All voltages are at the correct level. However, when I run my code, ( https://github.com/tmulroy/nodeBot/blob/master/bot_workspace/raspSpike.js) which just calls a servo.sweep(), my servo jitters a little bit, makes a high-pitch noise, then stops. I can see that it semi-sweeps: it rotates back and forth, but there's jitter and very little/slow movement. Any thoughts?
-Raspberry Pi 3
-Pi Cobbler (to breakout pi's gpio pins to breadboard)
I've seen two ways of interacting with PCA0685, I'm using a combo of both:
