5PCS KY-010 Photo Interrupter Module Arduino AVR PIC
Product 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.
