Last week, i create the second circuit to open and close the front door of Smart Mailbox using a arduino software. So, i found the circuit that did not using a arduino software. This circuit have using two push button, resistors, diode, capacitors, servo motor and LM555. finally i got a good result where the circuit i really good function.

For the first impression i want to make sure the the servo is function when both of button is pressed. Actually, i use the recyle components and already have one servo motor SG90 tower. So, i need to use it because want to save the budget. Furthermore, that also not a serious problem when i not use a real component like a photo. The servo and button can function but not really compatable with the voltage or resistance. So,i need to think harder how to modify and make it happen.
