- You can modify this project to perform different tasks at different times throughout the day, such as play howling noises at 8pm, or even play "Happy Birthday" on a specific date.
- Using a Motor FeatherWing you could expand this project to have the device operate physical noisemakers, such as banging pots and pans together, or clapping animatronic hands. Or you could create a cuckoo clock!
