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.

Tot slot

Once the TOT is inserted, it is housed in the TOT Slot for the duration of the game. Once the game is over, a solenoid actuates and pushes the TOT out to release it back to the user. The TOT was 3D printed and glued to the bottom of the overall housing.
