In this illustration we will going to wire the light interrupter. A photo interrupter is transmission type photo sensor that integrates optical receiving and transmitting elements in a single package please see the diagram below. Since the method involves light blocking commonly named photo interrupter. A long life infrared photo diodes is applied for output while a single photo transistor and photo IC are integrated on the other side for light detection.

Required Components



  • UNO / MEGA / NANO / PRO / DUE /  ESP8266 / AVR
  • Light Blocking Sensor / Photo Interrupter Sensor
  • 5mm / 3mm LED
  • 220 Ohms Resistor
  • Solder Less Bread Board
  • Jumper Wires / DuPont Wires
