Example Code for Arduino-Object Detection

Hardware Preparation

• DFRduino UNO R3 (or similar) × 1
• Infrared Proximity Sensor × 1

Software Preparation

• Arduino IDE

Wiring Diagram

Sample Code

int led = 13;  // Pin 13 has an LED connected on most Arduino boards.
int sensor = 8;
void setup() {
  pinMode(led, OUTPUT);   // initialize the digital pin as an output.
  pinMode(sensor, INPUT);
  digitalWrite(led, LOW);
}

void loop() {
  int val = digitalRead(sensor);
  if (val)
  {
    digitalWrite(led, HIGH);
  }
  else
  {
    digitalWrite(led, LOW);
  }
}

Result

When the detected object is in the detection range of the sensor, the LED corresponding to pin 13 of the UNO board lights up; when it's outside the detection range, the LED goes out.
