With strong reflectance, the output voltage tends towards GND; with weak reflectance, it tends towards Vcc. The resistor wired in series with the infrared LED sets the operating current to a safe ...

LED Indicator: The LED blinks in response to the sensor's detection of an object. The blinking behavior is controlled by the Arduino based on the sensor's output. Circuit Connections: IR Sensor VCC ...
