WOOT! I found the error after reading all lines of code that I had modified...
So now I'm back to square one: my code worked and yours didn't on the board, but I'll make a diagram to show my wiring exactly how I have it.
Here's my code:
#include <Keypad.h>
#include <Adafruit_NeoPixel.h>
// Define the states for the lock state machine
#define LOCKED 2
#define UNLOCKED 0
// State Variables: Initialize to the locked state
int LockState = LOCKED;
long StartTime = 0;
int position = 0;
int Distance = 0; //Record steps
// Define your password key sequence here
char* secretCode = "2301000";
// Keypad key matrix:
const byte rows = 4;
const byte cols = 3;
char keys[rows][cols] =
{
{'1', '2', '3'},
{'4', '5', '6'},
{'7', '8', '9'},
{'*', '0', '#'}
};
// Keypad pin definitions
byte rowPins[rows] = {5, 6, 7, 8};
byte colPins[cols] = {2, 3, 4};
// Instantiate the keypad
Keypad keypad = Keypad(makeKeymap(keys), rowPins, colPins, rows, cols);
int transistorPin = 9; //LED Transistor Pin Definition
int StepperDistance = 10; //Stepper Distance Pin Definiton
int StepperDirection = 11; //Stepper Direction Pin Definition
int StepperStart = 12; //Stepper Engage Pin Definition
int ColorLED = 13; //Color LED Definition
