Alex, an aspiring inventor keen on creating a basic locking mechanism for his room using an Arduino Uno board. He envisions a system where a push button serves as the key to open the door.

After some additional thoughts, Alex realized that his initial solution is very intuitive, and everyone can have access to his room. He Decides to improve on that and use a combination of many pushbuttons and storing a code in the memory of the Arduino board. A combination between those pushbuttons will be used to unlock the door.

Alex wants you to help achieving that project using the Arduino Board and the components you have available.
