Objective Here we’ll detect applause. The louder it gets, the brighter the light turns. When the brightness gets to the most, the buzzer will give an alarm.

Applause_heat Code description Control pin description #define PIN 4 Adafruit_NeoPixel strip = Adafruit_NeoPixel(6, PIN, NEO_GRB + NEO_KHZ800); #define mic_pin A0 #define buzzer_pin 6 Sound pre-set value #define voice 400 If the sound is louder than the pre-set value, the lamp will get brighter and when it reaches to a certain value, the buzzer will go off. if (voice_data > voice) { num++; if (num > 255) { num = 255; buzzer(); } colorWipe(strip.Color(num, 0, 0)); //delay(10); Serial.println(num); time = millis(); } Result The louder the applause gets, the brighter the lamp becomes. When it reaches to the brightest, the buzzer will give an alarm. When the sound gets below the pre-set value after that, it will take three seconds and then turn off the light and the buzzer.
