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:

 
int sensor = A1; //pin analogue A1 connected to sensor signal

void setup(){
  Serial.begin(9600); //initialisation of a serial monitor
  Serial.println("Reflective sensor test"); 
}

void loop(){
  int odl = analogueRead (sensor); //reading value from sensor
  Serial.println(odl); // display it on the monitor

  delay(200); // delay between readings
}

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:
