anti accident system using eye blink sensor

[mayankplayz]

For the people struggling with code here it is
#define Relay 13
#define buzzer A0
static const int sensorPin = 10; // sensor input pin
int SensorStatePrevious = LOW; // previousstate of the sensor

unsigned long minSensorDuration = 3000; // Time we wait before the sensor active as long
unsigned long minSensorDuration2 = 6000;
unsigned long SensorLongMillis; // Time in ms when the sensor was active
bool SensorStateLongTime = false; // True if it is a long active

const int intervalSensor = 50; // Time between two readings sensor state
unsigned long previousSensorMillis; // Timestamp of the latest reading

unsigned long SensorOutDuration; // Time the sensor is active in ms

//// GENERAL ////

unsigned long currentMillis; // Variabele to store the number of milleseconds since the Arduino has started

void setup() {
Serial.begin(9600); // Initialise the serial monitor

pinMode(sensorPin, INPUT); // set sensorPin as input
Serial.println("Press button");
pinMode(Relay, OUTPUT);
pinMode(buzzer, OUTPUT);
}

// Function for reading the sensor state
void readSensorState() {

// If the difference in time between the previous reading is larger than intervalsensor
if(currentMillis - previousSensorMillis > intervalSensor) {

// Read the digital value of the sensor (LOW/HIGH)
int SensorState = digitalRead(sensorPin);

// If the button has been active AND
// If the sensor wasn't activated before AND
// IF there was not already a measurement running to determine how long the sensor has been activated
if (SensorState == LOW && SensorStatePrevious == HIGH && !SensorStateLongTime) {
SensorLongMillis = currentMillis;
SensorStatePrevious = LOW;

Serial.println("Button pressed");
}

// Calculate how long the sensor has been activated
SensorOutDuration = currentMillis - SensorLongMillis;

// If the button is active AND
// If there is no measurement running to determine how long the sensor is active AND
// If the time the sensor has been activated is larger or equal to the time needed for a long active
if (SensorState == LOW && !SensorStateLongTime && SensorOutDuration >= minSensorDuration) {
SensorStateLongTime = true;
digitalWrite(Relay, HIGH);
Serial.println("Button long pressed");
}
if (SensorState == LOW && SensorStateLongTime && SensorOutDuration >= minSensorDuration2) {
SensorStateLongTime = true;
digitalWrite(buzzer, HIGH);
delay(1000);
Serial.println("Button long pressed");
}

// If the sensor is released AND
// If the sensor was activated before
if (SensorState == HIGH && SensorStatePrevious == LOW) {
SensorStatePrevious = HIGH;
SensorStateLongTime = false;
digitalWrite(Relay, LOW);
digitalWrite(buzzer, LOW);
Serial.println("Button released");


}

// store the current timestamp in previousSensorMillis
previousSensorMillis = currentMillis;

}

}

void loop() {

currentMillis = millis(); // store the current time
readSensorState(); // read the sensor state

}

Sir can please give the code, that you have used

[freeNode]

what sensor or module is this? where can I find it?

[SSundaresanPillaiA]

Bro can u send full vedio of doing this

[everythingisinfinity]

This ir sensor can do damage to eye or not

[a.sdharanidharan]

Sir I am a student we are going to make our project in our school so can you please send me the code you have used? Please

[swastikswaroop]

Sir where, I can find your code, please help me

Baki video me tho ardunoo Nano use hua hai par Apne Arduino r3 use kiya

Bro i need ur help. My circuit everything is ready. But problem is that when i close my eyes it doesn't work. So i asked help from of the engineering student he said u have to manage the sensitivity by using tester and moving the screw in eye blink sensor. So he says it depends on the light of the area is it?
