Description

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);

}

}
