Coding a clap switch with a timer between claps

Now, we will add a timer to limit the waiting timeframe between the first and second claps:

1. Define two new variables, both of the unsigned long type, to store the time of each clap. The changes to the previous sketch are highlighted:

   const int MicAnalogPin = 0; 
   const int LedDigitalPin = PC13; 
   const int ClapThreshold = 300; 
   int ClapNumber = 0; 
   bool LedState = false;
   unsigned long FirstClapEvent = 0;
   unsigned long SecondClapEvent = 0;

   These two highlighted variables will store the milliseconds when a clap is detected: one for the first time and another for the second time.

2. The setup() section remains unchanged, and we will continue to the loop() section to introduce the timer changes. We will add a conditional inside the conditional sentence for detecting a clap:

   void loop() {
     int SoundValue = analogRead(MicAnalogPin);  
     if (SoundValue > ClapThreshold) {
       ClapNumber...
