//***********************************************************************************************
//  This example shows how to use the basic methods of the FluxGarage Robo Eyes library. 
//
//  Hardware: You'll need a breadboard, a microcontroller such as arduino nano v3 or better an esp32, 
//  an I2C oled display with sh1106 chip and some jumper wires.
//
//  Use the dedicated I2C pins of your microcontroller, on ESP32-WROOM-32 module use pin 22 for SCL and pin 21 for SDA.
//  Please note: This example turned out to have slow refresh rates on Arduino Uno. Did not find a fix yet.

  // Define some automated eyes behaviour

  // Set horizontal or vertical flickering
  roboEyes.setHFlicker(ON, 2); // bool on/off, byte amplitude -> horizontal flicker: alternately displacing the eyes in the defined amplitude in pixels
