⚙️ Working Principle
Jab push button press kiya jata hai, PC817 ke input LED (Anode-Cathode side) me current flow hota hai. Internal infrared light phototransistor ko activate karti hai.
💡 LED ON = Optocoupler Working Properly
❌ LED OFF = Optocoupler Faulty or Damaged
Is tarah bina multimeter ke bhi optocoupler ki basic functionality test ki ja sakti hai.
