Create a simple locked box that will never open until you guess the correct combination of buttons. It will consist of a servo motor that will turn open when you enter the right combination in the keypad. If the password is incorrect, it will make an aggressive chiming sound on the Piezo speaker; if the password is correct, it will make a light chiming sound. You should be able to tell if the box is open or closed by looking at the LCD display. After 10 seconds of the Lock being open, it will close automatically.
Provide a schematic for the circuit and all the connective components such as the LCD, the piezzo. Please provide a code that compiles and works with feedback to show me what part of the arduino code is changeable, for instance the keypad code.
