Init commit with many years of arduino sketches and projects. I dont know if the esp8266 includes much, but there are also libraries. I hope they dont have crazy automatic versioning through the Arduino IDE.

+# JoystickController
+
+Fully compatible with SparkFun's [Arduino joystick shield](https://www.sparkfun.com/products/9760?). The library lets you easily fetch the current status of the joystick (demo video is [here](https://vimeo.com/49010406)). Implementation is quite simple;
+
+	JoystickController(int low = DEFAULT_LOW, int high = DEFAULT_HIGH)
+
+is a constructor. The first argument specifies the lower threshold value for the directional key pad, below which the controller is assumed to set left/down in the horizontal/vertical direction. The second argument specifies the upper threshold value, above which the controller is assumed to set right/up in the horizontal/vertical direction. If arguments are not specified, the following default values will be used:
+
+	static const int DEFAULT_LOW   = 490;
+	static const int DEFAULT_HIGH  = 530;
+
+For more information about the threshold see the following article; [How do I find the current direction of the joystick?](http://www.sparkfun.com/tutorials/171#direction)
+
+	void update()
+
+must get called in the main loop in order for the library to communicate with the joystick.
+
+	int getDirection()
+
+returns the current direction of the directional keypad as integer values that are defined as class static variables:
+
+	static const int DIRECTION_NONE       = 0;
+	static const int DIRECTION_UP         = 1;
+	static const int DIRECTION_UP_RIGHT   = 2;
+	static const int DIRECTION_RIGHT      = 3;
+	static const int DIRECTION_DOWN_RIGHT = 4;
+	static const int DIRECTION_DOWN       = 5;
+	static const int DIRECTION_DOWN_LEFT  = 6;
+	static const int DIRECTION_LEFT       = 7;
+	static const int DIRECTION_UP_LEFT    = 8;
+
+Finally buttons' status can be fetched from the following functions:
+
+	bool upButtonPressed()
+	bool downButtonPressed()
+	bool leftButtonPressed()
+	bool rightButtonPressed()
+	bool selectButtonPressed()
+
+They return true if a button is being pressed, otherwise false.
+
+## Example
+
+Here is a simple example for the library implementation.
+
+	#include "JoystickController.h"
+
+	JoystickController controller;
+
+	void setup(){
+		Serial.begin(9600);
+	}
+	
+	void loop(){
+		controller.update();
+
+		if (controller.selectButtonPressed()){
+			Serial.println("S");
+		}
+	
+		if (controller.upButtonPressed()){
+			Serial.println("U");
+		}
+
+		if (controller.downButtonPressed()){
+			Serial.println("D");
+		}
+
+		if (controller.leftButtonPressed()){
+			Serial.println("L");
+		}
+	
+		if (controller.rightButtonPressed()){
+			Serial.println("R");
+		}
+
+		int direct = controller.getDirection();
+	
+		switch (direct){
+			case  JoystickController::DIRECTION_UP:
+				Serial.println("UP");
+				break;
+			case  JoystickController::DIRECTION_UP_RIGHT:
+				Serial.println("UP-RIGHT");
+				break;
+			case  JoystickController::DIRECTION_RIGHT:
+				Serial.println("RIGHT");
+				break;
+			case  JoystickController::DIRECTION_DOWN_RIGHT:
+				Serial.println("DOWN-RIGHT");
+				break;
+			case  JoystickController::DIRECTION_DOWN:
+				Serial.println("DOWN");
+				break;
+			case  JoystickController::DIRECTION_DOWN_LEFT:
+				Serial.println("DOWN-LEFT");
+				break;
+			case  JoystickController::DIRECTION_LEFT:
+				Serial.println("LEFT");
+				break;
+			case  JoystickController::DIRECTION_UP_LEFT:
+				Serial.println("UP-LEFT");
+				break;
+		}
+
+		delay(100);
+	}
