Caja Fuerte (safe box)

grabcad

Secure box printed with servo-controlled lock. All screws are placed from the inside so that once closed it cannot be disassembled. In the back there are holes to mount an Arduino Nano with its shield, allowing power to be connected from outside. On the door is a hole for a button. I have installed a toggle switch on the button, connected to a digital input of the Arduino to enable or disable opening. To give the order to open it can be used the same button, Bluetooth communication, RFID... whatever comes to mind. In this case I'm controlling it by Bluetooth.
