/*Nakul Verma, Student # 12345
First code to try and validate all the individual components connected to this
Arduino Uno. Component list is as follows:

Pushbutton circuits that generate a logic high are connected to digital pins:
2 - Button A (Red)
12 - Button B (Blue)
8 - Button C (Yellow)
7 - Button D (Green)

LEDS cicuits are on the following digital pins:
5 - Orange LED
6 - Blue LED
10 - Green LED
9 - Red LED

Servo control line is on digital pin 11
