7 SEGMENT DISPLAY COUNTER CIRCUT

It is a simple circuit to drive the 7 segment display. The circuit consist of a 555 timer IC and CD4033 counter IC. The main components required are

• CD4033 counter IC
  
• 555 timer IC
  
• 7 Segment Display
  
• Resistors
• Capacitors
• Bread board or PCB
  
• A suitable power supply of 5V DC

                 The working of the circuit as same as mentioned in my Running LED project. The 555 Timer is used in astable mode of operation and the generated clock pulse is given to the clock input of the counter IC. You can also implement the circuit using CD4017 IC. The circuit and calculations are same as in my Running LED project.
