sound sensors
Sound sensors (called auditory sensors) uses are pretty much self explanatory including clap, voice, safety and noise activated applications
The programming for the Arduino microcontroller uses a switching threshold of 10. The threshold can be adjusted depending on the load. Switching of a plethora of possible load devices is made by using a relay module. The following code is to make the Arduino UNO control a 115volt lamp using a 5volt relay activated by sound.
