Puppet theatre with Touch sensors

  • The characters are built on the screen of the puppet theatre.
  • The little boy “sits” in the middle, his head is moved by a servo motor.
  • The cloud and the car are moved by 2 DC motors on each side.
  • There are 2 buttons on each side of the robot, which move the actors in the scene separately.
  • As long as the Touch sensor is pressed, the DC motor and the actuator connected to it will move.
  • The boy in the centre moves his head to the right or left, depending on which side the Touch sensor is pressed.

Puppet theatre activated by IR photoreflector

  • There are 1-1 IR photoreflector on each side of the puppet theatre.
  • The boy in the middle is set in motion by a DC motor.
  • The bottom sensor has a red LED, the top sensor a white LED.
  • The lower IR photoreflector is activated by the small car, the upper one by the cloud.
  • When the IR photoreflector is covered, the boy starts moving at different speeds and the corresponding LED flashes.
  • When you move the car or cloud away from the IR photoreflector, the movement and flashing stops.
