Step 4: Start Assembly

  • Cut a rectangle at the bottom on the box so that the screen is exposed and stuck.
  • Cut two round holes beside the screen to expose the Ultrasonic Wave Detector.
  • Also cut a small rectangle on the back of the box to connect with the computer (be tight).
  • Leave the wires in the box.
  • Cut a rectangle on the side to take out the motor.
  • Sealed off the box.
  • Stick the motor in the cylinder.
  • Put a small sector on the motor (to make it move).
  • A big sector is glued under the motor, in this way, when the motor rotates, there will be a hole for the medicine to fall off.
