After finish created the Smart Mailbox casing, i want to create other circuit to open and close for customer or postman. Actually this system easily to customer or postman where sending their item into the Smart Mailbox. Furthermore, this system also want to prevent the item from stolen or loss from the other people. 

This photos is simple circuit where using the arduino coding to trigger the buttons as a input. The green button show as limit switch sensor. That sensor i was create to trigger the open button where the open button cannot function when the sensor is ON. But, the circuit not function because have a problem with the arduino coding. So, i need to find another ways to make it really finction.
