// Build a door lock system using the keypad you built in the GPIO questions, a servo, a red LED, and
// a green LED. The system should prompt the user to enter a 4-digit code using the keypad. Upon
// entering the code, the system should compare it with a code hardcoded in your application. If the
// entered code matches the hardcoded code, rotate the servo 90 degrees, then light up the green LED, indicating
// that the door is unlocked. Otherwise, if the entered code does not match the hardcoded code,
// the red LED should light up, indicating that the door is still locked.
