LittleBits Hack-O-Lantern is a fun Halloween pumpkin kit that is illuminated by sound. LittleBits makes a variety of modular electronic toys, so it's no surprise that it released this holiday DIY for kids. The sound-activated jack-o-lantern is made with three "Bits" from LittleBits, including a bright LED light, a power source and a sound trigger, so that the pumpkin is able to light up when you clap.
In order for best results, LittleBits suggests using a medium sized pumpkin, and you can trace any design you'd like onto the pumpkin. Alternatively, LittleBits also has a template that you can download as a PDF to make things even easier. As well as being a great Halloween project, it's also a safe and fun learning experience when it comes to electronics and circuitry.
