Control Pin Description #define pushButton 4 //Vibration #define speakPin 6 //Buzzer Judge if there is vibration in two seconds. if (millis() - time > 2000) { if (!digitalRead(pushButton)) shock = false; time = millis(); } When detecting vibration, the buzzer will set alarm for twice repeatedly. Users can change alarm times. if (shock) { for (int j = 0; j < 2; j++) buzzer(); } else noTone(speakPin); Result When knocking on the vibration sensor, the buzzer will make alarm twice and will stop when there is no vibration after the alarm. You can also build a beautiful shell with LEGO for the project since mCookie can be easily stacked with LEGO boards. 。 Video
