smart-lock

The smart lock consists of 4 potentiometers that each represent an AnalogIn. Adjusting the potentiometers would adjust the distinct digits. It is important to note that this is a 4 digit combination.

Validation

The security lock consists of a validation mechanism, where it checks to see if the current combination entered is equal to the set combination. The board provides LED indicators along with an LCD display that does the indication if the combination is incorrect or correct.

Set

The security lock consists of a set mechanism, where there is a requirement that the user must first perform validation, then they may set the combination using the set button, which calls the reset ISR. This changes the bitmode and it is decided in a switch statement for it to either perform the set or the validation. There is an enterBit that if true, validation upon the current and set combinations consist of equal digits.
