KY-010 Photo Interrupter Sensor Module Light Blocking Break Beam Optocoupler for Arduino MCU DIY Starter Learning Board Componen

High-concerned chemical : none is_d : Yes Output : Digital Sensor Brand Name : SZYTF Origin : Mainland China Use : Position Sensor

Light-blocking module KY-010 The light-blocking module and the digital 13 interface come with an LED to build a simple circuit and create a light-blocking indicator light By using the LED that comes with the digital 13 interface, connect the light-blocking sensor to the digital 3 interface. When the light-blocking sensor detects a key signal, the LED lights up; otherwise, it turns 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); } } aeProduct.getSubject()
