The magical pigskin and the stove’s fire - The stove

Programming level 1

Directly driven gear mechanism

P1

How to build

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.

  • The structure of the characters and the stove tray does not change from P1. However, the stove door can be opened and closed by a DC motor.
  • Door opening and closing, as well as tray opening and closing, is controlled by a Touch sensor each.
  • Press one Touch sensor to open the door and the tray comes out of the stove, and press the other to return the tray to the inside of the stove and close the door.

Servo motor opening mechanism

  • The structure of the characters and the stove tray does not change from P1.
  • The stove door opens with a servo motor.
  • The door of the stove is controlled by an infrared sensor, and when the princess is placed in front of it, the stove door opens and the tray rolls out.
  • Press the Touch sensor and the tray rolls back into the stove and the door closes.

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.
