This project is part of an extensive research on the use of animatronics and interactive objects that I have been developing. It is an investigation into the possibility of creating an algorithmic script for a comic object.The code is quite simple and is based on the notion of dramatic time and rhythm and is enough to make it feel like the Servo Motors are establishing some sort of secret communication. As the PCA9685 module supports up to 16 servos, the system can be used to simulate a crowded environment, such as a fair or trade. With the characters talking to each other.The two figures in the project's cover photo are designed to be attached to the servo motors and move their mouth when the servos are actuated.Two versions of the same idea follow. The first eliminates the use of the PCA9685 module, connecting the servos directly to the Arduino. In the second, it is possible to expand the system, connecting up to 16 Servo Motors at the same time.#include <Wire.h>
