+
+Adding Additional LED's
+-----------------------
+Simply add an LED and PushButton to the circuit parallel to the others.
+
+Now just add the port of the LED to:
+
+
+
+Features
+--------
+- Extensibility: More LEDs and switches can be added to the circuit and an array in the code. The code is written with a non-specific led amount in mind.
+- Simplicity: An easy game to understand, with a simple design
+- Multiple levels: The game continues to level 100, this can be changed in code easily by changing the constant variable in the code.
+- Failure: The game clearly states failure by flashing all the LEDs
+- Makes use of Push Buttons and LEDs
+- Modular code
+
+Instructions
+------------
+- The goal of the game is to copy the sequence of lights.
+- Each button corresponds with an LED, the goal of the game is to remember the sequence of lights presented by the arduino and copy it.
+- The arduino will display a light, press the button corresponding with that light.
+- The computer will then add another light to the sequence, you must then repeat the sequence using the buttons.
+- If you fail to enter the sequence correctly, all of the LEDs will light up, meaning that you have failed! The game will then restart.
