Directly driven gear mechanism

  • All characters and the stove door are equipped with a shaft, so that all the characters in the scene can be moved.
  • The tray coming out of the stove moves with the help of 1 DC motor on a drive rail and a gear, which can be switched on and off directly with the switch on the battery box.

Automatic mechanism

P4

How to build

Automatic mechanism

  • The scene is identical to P3, but instead of a Touch sensor, an infrared sensor is built into the tray.
  • The door of the stove opens and the tray comes out when you place the princess in front of the infrared sensor.
  • In this scene, however, we place the pigskin on the tray of the stove, on the built-in infrared sensor.
  • This triggers the return of the tray to the stove and the closing of the door.
