KY-010: Optical broken module

Arduino KY-010 Optical broken module

KEYES ARDUINO photo interrupter module

Photo interupter module use the buildin arduino led. If the sensor is broken the LED is turned on.

Device senses a signal, LED lights, otherwise off.

Schematic

If you view from the top like on the photo

  • Left = Ground
  • Middle = +5V
  • Right = Signal

Connect the module to the arduino as follows:

  • Arduino pin GND to module GND
  • Arduino digital pin 3 to module Signal
  • Arduino pin 5V to module 5V

Example Code

// Example code for KY-010
// photo interrupter module

int Led = 13 ;// define LED Interface
int buttonpin = 3; // define the photo interrupter sensor interface
int val ;// define numeric variables val
void setup ()
{
  pinMode (Led, OUTPUT) ;// define LED as output interface
  pinMode (buttonpin, INPUT) ;// define the photo interrupter sensor output interface   
}

void loop ()
{
  val = digitalRead (buttonpin) ;// digital interface will be assigned a value of 3 to read val
  if (val == HIGH) // When the light sensor detects a signal is interrupted, LED flashes
  {
    digitalWrite (Led, HIGH);
  } else {
    digitalWrite (Led, LOW);
  }
}
