BCD Counter Circuit


Circuit Diagram 01

BCD Counter circuit use for count up to  0-9. NE555  timer  use to make pulse to drive counter part of circuit, but you can add debounce  less switch  ( Circuit Diagram 02)  without timer. 

For real world simulation 

Circuit Diagram 02

Parts List for Circuit Diagram 01

  • Common Cathode 7 Segment     
  • NE555                                  
  • 74LS160                              
  • 4511
