An example of a project for the ky-010
//Author: Danny van den Brande, arduinosensors.nl //Hello world! I made a simpel example on what you can do with the KY-010 //In this case we made a simpel alarm with a piece of plastic, //i used a atm card to put in the sensor any piece of plastic will work, //when you remove it the alarm will trigger and print a value and text in the serial monitor. //You can make it print on a lcd to, or for more advanced stuff make it send a sms or add relays, whatever you want it to do! int PhotoElectricSensor = A0; int buzzer = 7; int RedLed = 4; int GreenLed = 5; int BlueLed = 6; int val ; void setup () { Serial.begin(9600); pinMode (buzzer, OUTPUT) ; pinMode (RedLed, OUTPUT) ; pinMode (GreenLed, OUTPUT) ; pinMode (BlueLed, OUTPUT) ; } void loop () { val = analogRead (PhotoElectricSensor) ; Serial.print(val);// printing the value in the serial monitor if(val < 50&& val < 500) { Serial.println(" ATM CARD NOT PLACED");// Open the serial monitor to see this. digitalWrite (GreenLed, LOW); alarmsound(10);// Change if you want the alarm to last longer if card is removed } else if (val > 500 && val < 1023) { Serial.println(" ATM CARD IN PLACE");// the alarm will not trigger and the green led will be on. digitalWrite (GreenLed, HIGH); } delay(1000); } void alarmsound(int duration){ // alarm section, alarm will flash red and blue when trigger, if not it will stay green. for (int p = 0; p < duration; p++){ for (int i = 0; i <80; i++) { digitalWrite (buzzer, HIGH) ; digitalWrite (RedLed, HIGH) ; delay (1) ; digitalWrite (buzzer, LOW) ; digitalWrite (RedLed, LOW) ; delay (1) ; } for (int i = 0; i <100; i++) { digitalWrite (buzzer, HIGH) ; digitalWrite (BlueLed, HIGH) ; delay (1) ; digitalWrite (buzzer, LOW) ; digitalWrite (BlueLed, LOW) ; delay (1) ; } } }
