7)Screws

8)Wooden body

There is nothing special about the structure , just three wooden body is attached in a favourable manner which is shown in the picture

If you look at the metal sheet in the circuit, it is connected to the D5 to the Arduino nano. When the hammer comes to the loading position a single piece of wire connected to the hammer comes in contact with the metal sheet and thus gives a signal to the Arduino. As a result, the Arduino nano turns on the servo and the servo pulls the ac motor away from the gear set and thus releases the hammer .
