Sometimes when you come back from school or work, you come back exhausted. So you immediately go to your bedroom, and after getting comfortable in bed you realize that the light is still on, and the light switch is a 15 feet trip. What if, with a single clap you can turn off the light? This project is about turning the light off from a long distance. In order to achieve that, a sound sensor was built and connected to a photon particle that does communicate with another photon particle to turn off the light.
The way the sound sensor works is by making it close to the threshold frequency and to achieve that, a variable resistor had to be changed to make the sound sensor close to the threshold, which means that the sound sensor becomes sensitive to sound. At that point the sound sensor becomes like variable resistor, but instead of changing the resistance mechanically, the resistance will be changing audibly. For example, by clapping, or snapping fingers. As it receives the signal, it sends it to the other photon that turns the light on upon snapping fingers or clapping and then off upon repeating it. After the light turns on or off, another signal is setback from the second photon to the first photon that acknowledges receiving the signal from the sound sensor.Demonstration
