Controlling servo in Elixir/Nerves
So I decided to write one on my own, reading PCA9685 data sheet and adopting ideas from existing libraries written in various programming languages. My servo kit is working pretty well so far.

[Elixir/Nerves] Smoothly dimming LEDs using a servo driver
Using an external servo driver board like Adafruit 16-Channel PWM/Servo HAT for Raspberry Pi, we have more flexibility with more channels. The downside was there was no library for using that servo driver; however as I studied Adafruit's official python code, it was not easy but not rocket science either. So I decided to write my own library in Elixir. It would be great if it helps other alchemists. The key thing is that board uses PCA9685 PWM controller, so the chip's data sheet is the single source of truth.

Controlling servo in Elixir/Nerves
I could not found any Elixir libraries for controlling a servo other than jimsynz/pca9685.ex, which was unfortunately outdated and unmaintained.
What are some alternatives?
When comparing servo_kit and pca9685.ex you can also consider the following projects:
cubdb - Elixir embedded key/value database
nerves_livebook - Develop on embedded devices with Livebook and Nerves
kiwi - Pimoroni Keybow based, WiFi-enabled Macro Pad (a.k.a. poor-man's Elgato Stream Deck)
circuits_i2c - Communicate over I2C from Elixir
nerves - Craft and deploy bulletproof embedded software in Elixir
