Introduction: Laser Security System Using Arduino UNO and LDR Module.
This amazing project is small miniature model of how things are safeguarded in museum,banks and....etc.
-Project by
cadet Kartik Patil
Step 1: Supplies
Materials used are ;
- Arduino UNO(it is micro-controller board based on the A T mega328p.)
LDR(light dependent register)this unique sensor is sensitive to light.
Laser
Beeper
LED (red)
Mirrors
A wooden
plywood
Jumper cables
Step 2: Procedure
Take a wooden board.Place 4 mirrors on it. These mirrors have to be placed in such a way that,the rays reflected by them would be at 90 degree.As shown above
Step 3: Schematic of the Model
Step 4: Conclusion
The concluding part is programming and here are the codes;
<p>int sensorPin =A0;<br> int led1 = 3; int sensorValue =0;</p><p>void setup() { Serial.begin(9600); pinMode(led1,OUTPUT);</p><p>}</p><p>void loop() { sensorValue = analogRead(sensorPin); Serial.println(sensorValue);</p><p>if(sensorValue > 80) {</p><p> digitalWrite(3,HIGH); delay(3000);</p><p>}</p><p>if(sensorValue <50 ) {</p><p> digitalWrite(3,LOW); } }</p><p>In your case their may be the need to change the sensor values. If u have done it then kindly comment me.</p><p> <strong><em><u> https://www.facebook.com/Atlssbj/videos/831609087241705/</u></em></strong></p><p> !!All the best !!</p>
