/***************************************************
|
||||
|
This is an example for our Adafruit 16-channel PWM & Servo driver |
||||
|
Servo test - this will drive 8 servos, one after the other on the |
||||
|
first 8 pins of the PCA9685 |
||||
|
|
||||
|
Pick one up today in the adafruit shop! |
||||
|
------> http://www.adafruit.com/products/815
|
||||
|
|
||||
|
These drivers use I2C to communicate, 2 pins are required to |
||||
|
interface. |
||||
