//***********************************************************************************************
//  This example shows how to use the basic methods of the FluxGarage Robo Eyes library.
//
//  Hardware: You'll need a breadboard, an arduino nano r3, an I2C oled display with 1306
//  or 1309 chip and some jumper wires.

#include <Adafruit_SSD1306.h>

#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels
// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
#define OLED_RESET     -1 // Reset pin # (or -1 if sharing Arduino reset pin)
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

#include <FluxGrage_RoboEyes.h>
roboEyes roboEyes; // create RoboEyes instance


void setup() {
  Serial.begin(9600);

  // Startup OLED Display
  // SSD1306_SWITCHCAPVCC = generate display voltage from 3.3V internally
  if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) { // Address 0x3C or 0x3D
    Serial.println(F("SSD1306 allocation failed"));
    for (;;); // Don't proceed, loop forever
  }

  // Startup robo eyes
  roboEyes.begin(SCREEN_WIDTH, SCREEN_HEIGHT, 100); // screen-width, screen-height, max framerate

  // Define some automated eyes behaviour
  roboEyes.setAutoblinker(ON, 3, 2); // Start auto blinker animation cycle -> bool active, int interval, int variation -> turn on/off, set interval between each blink in full seconds, set range for random interval variation in full seconds
  roboEyes.setIdleMode(ON, 2, 2); // Start idle animation cycle (eyes looking in random directions) -> turn on/off, set interval between each eye repositioning in full seconds, set range for random time interval variation in full seconds

  // Define eye shapes, all values in pixels
  //roboEyes.setWidth(36, 36); // byte leftEye, byte rightEye
  //roboEyes.setHeight(36, 36); // byte leftEye, byte rightEye
  //roboEyes.setBorderradius(8, 8); // byte leftEye, byte rightEye
  //roboEyes.setSpacebetween(10); // int space -> can also be negative

  // Cyclops mode
  //roboEyes.setCyclops(ON); // bool on/off -> if turned on, robot has only on eye

  // Define mood, curiosity and position
  //roboEyes.setMood(DEFAULT); // mood expressions, can be TIRED, ANGRY, HAPPY, DEFAULT
  //roboEyes.setPosition(DEFAULT); // cardinal directions, can be N, NE, E, SE, S, SW, W, NW, DEFAULT (default = horizontally and vertically centered)
  //roboEyes.setCuriosity(ON); // bool on/off -> when turned on, height of the outer eyes increases when moving to the very left or very right

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

  // Play prebuilt oneshot animations
  //roboEyes.anim_confused(); // confused - eyes shaking left and right
  //roboEyes.anim_laugh(); // laughing - eyes shaking up and down

} // end of setup


void loop() {
  roboEyes.update(); // update eyes drawings
  // Dont' use delay() here in order to ensure fluid eyes animations.
  // Check the AnimationSequences example for common practices.
