Arduino and the KTIR0711S reflective sensor

Arduino and Reflective Sensor KTIR0711S

A short guide showing how to connect Arduino and the bounce sensor.

The following elements are used in the example:

Connecting the sensor from Arduino:

To operate the sensor with Arduino, connect the circuit as follows:

Sensor Pin Arduino
GND GND
OUT A1
VCC 5 V

Program for Arduino

The following code was used in the example:

  1.  
  2. int sensor = A1; //pin analogue A1 connected to sensor signal
  3.  
  4. void setup(){
  5.   Serial.begin(9600); //initialisation of a serial monitor
  6.   Serial.println("Reflective sensor test"); 
  7. }
  8.  
  9. void loop(){
  10.   int odl = analogueRead (sensor); //reading value from sensor
  11.   Serial.println(odl); // display it on the monitor
  12.  
  13.   delay(200); // delay between readings
  14. }

The values read on the serial monitor decrease as you approach an obstacle. The effects of the program can be observed on the screen below:
