Figure 1-1. A Whistle Controlled Light Switch

For our final project, we built a whistle controlled light switch. We were motivated by the daily struggle of getting out of bed to turn on/off the light. You can attach our final product on any light switch that can be commonly found in U.S. households. Once a correct sequence of whistle frequencies is detected, light switch will be mechanically toggled. You can turn on the light with a monotonically increasing whistle melody, and turn off with a monotonically decreasing.
