Decade counter ic cd4026 or cd4033 whichever available can be used as counter cum display driver. Here we have used a timer ne555 as an astable oscillator with a frequency of about 100 hz. 4 digit 7 segment display has four seven segment display joined together or we can say multiplexed together.
When using cd4026 pin 14 cascading output is to be left unused open but in case of cd4033 pin 14 serves as lamp test pin and the same is to be grounded.
