Please refer to the following links for more information:
- This servo motor control hat is based on the PCA9685 device. The PCA9685 product data sheet (https://cdn-shop.adafruit.com/datasheets/PCA9685.pdf) contains full information about operating this chip. I highly recommend referencing this.
- I also recommend looking at the SG90 servo motor data sheet (http://www.ee.ic.ac.uk/pcheung/teaching/DE1_EE/stores/sg90_datasheet.pdf) for information about their operation.
- The AdaFruit guide to the pan and tilt mechanism (https://learn.adafruit.com/mini-pan-tilt-kit-assembly) has a set of assembly instructions. They are in a slightly different order from mine but may give a different perspective if this is proving to be tricky.
