PicoBricks Money Box can detect objects placed in its receptacle through distance sensor in the front of it and automatically lifts its receptacle to take in these objects.

In this project, when the distance sensor detects the object placed in the receptacle , the servo motor connected to the motor driver is adjusted to the angle specified in the code, and then the object inside the receptacle is dropped into the Money Box.

You can assemble this project by breaking apart the PicoBricks modules at the proper points.
