The module used here is a self-contained, compact common-cathode Create electronic circuit diagrams online in your browser with the Circuit Diagram Web Editor. Write excitation table of Flip Flop –. Aim of this project is very simple it counts Objects or Pulses from IR proximity detector. Push button switch. Connect the ground (black) wire to any pin of the display.
