A tiny hack against the dark, using Lilypad Arduino.

When the light level falls and it starts to get dark, an LED switches on, and the buzzer plays a short tune to ward away the darkness.

This hacked buzzer plays a few bars of Do Re Mi. After all, if Julie Andrews can’t chase away the darkness, who can?

Uses a light sensor, LED, Lilypad buzzer.

With thanks to MTU’s frequency of musical notes and Leah Buechley’s sound code.
