Special gear and driverail mechanism to symbolise crying
- Build Alice's head and the gear-driverail structure based on the sample, with the tears being "pushed" out through Alice's eyes by the DC motorised structure.
- Connect 2 Touch sensors, Buzzer and 2 LEDs.
- The program starts when one of the Touch sensors is pushed.
- The DC motor stops, the LEDs start flashing and the Buzzer sounds, confirming the crying when the other Touch sensor is pushed.
