AOUT	A0	Analog data output
DOUT	D2	Digital data output

Examples

• Please download and install Arduino IDE to your PC.
  • Arduino Website
• Download the demo codes, unzip them, and find the Arduino examples.
• Open the Infrared_Proximity_Sensor.ino file by the Arduino IDE.

• Build and upload the codes to the UNO board.
• After uploading, you can open the Serial Monitor of IDE and check the data.

Expected result

• The indicator of the sensor lights up when the sensor is close to the obstacle and goes off when it is away from the obstacle.
• As the distance between the sensor and the obstacle changes, the output data of the serial port changes accordingly.
