V3 should be much better and versatile.</p><p>arduino code:</p><p>//pin<br>const int buzzerPin = 2;<br>const int ledPin = 1;<br>const int motionPin = 0;<br>int sensorValue = LOW;</p><p>void setup()<br>{<br>pinMode(ledPin,OUTPUT);<br>pinMode(buzzerPin,OUTPUT);<br>pinMode(motionPin,INPUT);;<br>digitalWrite(ledPin, LOW);<br>digitalWrite(buzzerPin, LOW);<br>}</p><p>void loop()<br>{<br>sensorValue = digitalRead(motionPin);<br>if ( sensorValue == HIGH) {<br>tone(buzzerPin, 1200);<br>digitalWrite(ledPin, HIGH);<br>delay(100);<br>noTone(buzzerPin);<br>digitalWrite(ledPin, LOW);<br>delay(100);<br>}<br>else {<br>noTone(buzzerPin);<br>digitalWrite(ledPin, LOW);<br>}<br>}</p>
