==Introduction==
Infrared obstacle avoidance sensor is equipped with distance adjustment function and is especially designed for wheeled robots.<br>
This sensor has strong adaptability to ambient light and is of high precision. It has a pair of infrared transmitting and receiving tube. <br>
When infrared ray launched by the transmitting tube encounters an obstacle (its reflector), the infrared ray is reflected to the receiving tube, after a comparator circuit processing, the indicator will light up. <br>
You can adjust the detection distance by rotating the potentiometer knob, the effective distance range of 2~40cm. <br>
They can be widely used in robot obstacle avoidance, avoidance car, line count, and black and white line tracking and many other occasions.<br>

<br>
==Upload the Code==
Copy and paste below code to [http://wiki.keyestudio.com/index.php/How_to_Download_Arduino_IDE Arduino IDE] and upload. 
<pre>
const int sensorPin=6;// the sensor pin
const int ledPin=13;// the LED pin
int sensorState=0;// variable for reading the sensor status
void setup(){
pinMode(ledPin,OUTPUT);
pinMode(sensorPin,INPUT);
}
void loop() {
// read the state of the sensor value:
sensorState=digitalRead(sensorPin);
// if it is, the sensorState is HIGH:
if(sensorState==HIGH){
digitalWrite(ledPin,HIGH);
}
else{
digitalWrite(ledPin,LOW);
}}
</pre>

<br>

==What You Should See==
Done uploading the code, when the sensor detects an obstacle, the led is turned on.
