[Doraemon Gadget] 0002-Time Machine 2.0-Sound and Light Effect Version

I previously made a small version of the time machine, and when I was making it, I thought about turning the lights on top into a night light. So, I scaled up the model, added some electronic components, and made it into a small night light that can play the Doraemon theme song.

Parts list:

1. 3mm through-hole multi-color LED bead x 1
2. 3.7v model battery x 1
3. Two-position small toggle switch SMTS-102 x 1
4. Mouse micro switch with lever 1A125V x 4
5. Serial port voice module MP3 chip audio playback board x 1
6. 16mm round internal magnetic mini speaker x 1
