Arduino n00b here. I currently have an Arduino Nano set up to run 6 servos from a PCA9685 board. I'm looking to add 6 switches and 6 LED indicators to switch servo positions. What I'm curious about is how to connect the WS2818B. I know they can be run through I2C, but the Pca9685 is using those wires. Can I run both the pca9685 and the LEDs through I2C or just run each LED through a separate pin?

I was looking at WS2818B datasheet, they do not use i2c. It just needs a single ( dedicated) pin to receive the color/brightness commands.
