This is an example for our Adafruit 16-channel PWM & Servo driver
Servo test - this will drive 16 servos, one after the other
Pick one up today in the adafruit shop!

These displays use I2C to communicate, 2 pins are required to
interface. For Arduino UNOs, thats SCL -> Analog 5, SDA -> Analog 4

persze csak 1 pillanatra lett túlvezérelve kalibrálás közben 
), illetve hogy milyen gyorsan tegye meg a servo kar az utat.
