Code for MidTerm 1

Component list is as follows:
Pushbutton circuits that generate a logic high are connected to digital pins:
2 - Button A
12 - Button B
8 - Button C
7 - Button D

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

Servo control line is on digital pin 11
