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

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

Servo control line is on digital pin 11

#include <Servo.h>      //Includes servo library
Servo wiggly;           //Creates servo object named "wiggly"

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

  //designate pushbuttons pins as inputs
  pinMode(2, INPUT);
  pinMode(12, INPUT);
  pinMode(8, INPUT);
  pinMode(7, INPUT);

  //designate LED pins as outputs
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);

  //designate pin 11 as the servo PWM pin

int once = 1;   //Makes a variable so that certain actions only exicute once

void loop()
  // put your main code here, to run repeatedly:
  //This if statement will only exicute once when the program starts
  if(once == 1)
  //Turn all LEDs off
    digitalWrite(5, HIGH);
    digitalWrite(6, HIGH);
    digitalWrite(9, HIGH);
    digitalWrite(10, HIGH);
    //Changes the once variable so that this if statement never exicutes again
    once = 0;
