//GOAL: check that servo moves and turn on LED

// Include servo library for the Servo motor
#include <Servo.h>

// Define pin number to LED
int tled = 11; // turquoise led connected to pin 11

int ServoPin = 12; // Servo is attached to pin 12
Servo myservo; // The servo motor is called myservo
int pos = 0; // Variable to store servo motor's position (in degrees)

const int up = 0;
const int down = 180;

int xPin = A0; // horiz (blue wire)
//int yPin = A1; // vert (green wire)
int buttonPin = 9; // joystick button (magenta wire)
int xValue;
//int yValue; 
int buttonState; // is button pressed or unpressed?
int angle;

void setup() {
  // put your setup code here, to run once:

  //Define LED as an output
  pinMode(tled, OUTPUT);

  //Initially, turn off LED
  digitalWrite(tled, HIGH);

  //Set up servo motor
  myservo.attach(ServoPin); // attach servo motor to its pin (pin 12)
  myservo.write(0); // set initial servo position to be 0 degrees

  Serial.begin(9600);
  pinMode(xPin, INPUT);
  //pinMode(yPin, INPUT);
  pinMode(buttonPin, INPUT_PULLUP);
}

void loop() {
  // put your main code here, to run repeatedly:
  
  /*
  //turn on LED for 2 seconds
  digitalWrite(tled, LOW);
  delay(2000); 
  // turn off LED for 5 seconds
  digitalWrite(tled, HIGH);
  delay(5000);

  //point servo up and down
  myservo.write(up);
  delay(500);
  myservo.write(down);
  delay(500);
  */

  xValue = analogRead(xPin);
  //yValue = analogRead(yPin);
  buttonState = digitalRead(buttonPin); // digital is between pushed and unpushed
  //unpushed = high = 1, pushed is opposite

  if(buttonState == 0)
  {
    digitalWrite(tled, LOW);
    delay(2000);
  }
  
  // Map joystick range to servo angle (0–180 degrees)
  angle = map(xValue, 0, 1023, 0, 180);

  myservo.write(angle);  // Move servo to that angle
  
  // Optional: print for debugging
  Serial.print("Joystick: ");
  Serial.print(xValue);
  Serial.print(" | Servo Angle: ");
  Serial.println(angle);

  delay(15);  // Small delay for stability

  
  

  //NOTE: this servo moves 180 degrees, not 360 degrees
