1-20PCS KY-010 Broken Light Blocking Photo Interrupter Sensor Module For AVR PIC DIY Starter Kit KY010

High-concerned chemical : none is_d : Yes Dissipation Power : n/a Supply Voltage : n/a Application : Computer Type : Voltage Regulator Brand Name : SZYTF Origin : Mainland China Condition : New Operating Temperature : n/a

Photo interrupter module and a digital interface, built-in 13 LED build a simple circuit to produce.photo-interrupter warning lamp  It comes with digital interfaces of the LED, the light blocking access number 3 sensor interfaces,sensing when the light interrupter  Device senses a key signal, LED lights, otherwise off.  Routines source code:  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);  }  }
