Watering can
The watering can was 3D printed and a vibration motor was attached to the base of the watering can. The watering can was used to "water" whichever blue LEDs lit up. If the correct blue LED was "watered", the IR LED would detect it and the vibration motor would turn on to give a tactile feedback to the user.
