 Clap detection function features:

   * Detects if so many claps within a short period of time and disables for some time the clap detection feature. This feature allows noise detection having a safety purpose, so the switch and light do not turn on and off so many times in a short interval if there is noise inside the house.
   * There are 3 versions of clap detection function which are implemented. The last version does an average reading on the digital input pin and performs average on the reading values. This feature is also added for robustness, so small microphone noise inputs to be ignored.
