Description
This infrared sensor is designed primarily to allow wheeled robots to follow lines. The sensor is comprised of an infrared transmitter/receiver pair emitting a certain IR frequency to detect reflectivity with high precision. The reflectivity threshold can be changed by adjusting the potentiometer, allowing you to set the sensitivity of the module.
Test Code
int Led = 13; // define LED Interface
int buttonpin = 3; // define tracing sensor interface
int val; // define numeric variables val
void setup () {
pinMode (Led, OUTPUT); // define LED as output interface
pinMode (buttonpin, INPUT); // define tracing sensor output interface
}
void loop () {
val = digitalRead(buttonpin); // digital interface will be assigned a value of 3 to read val
// When the sensor detects a tracking signal, LED flashes
if (val == HIGH) {
digitalWrite(Led, HIGH);
}
else {
digitalWrite(Led, LOW);
}
}
