This video is about the digital counter from (0-99) by 7 segment display, for that we used 555,CD4026 IC., 4026 is an IC which can perform the function of both a counter as well a 7-segment Driver. One single IC can be used to count form zero (0) to nine (9) directly on a Common Cathode type 7-segment display. The count can be increased by simply giving a high clock pulse, also more than one digit (0-9) can be created by cascading more than one CD4026.
For two digit counter we're going to connect one more 4026 ,then connect div10 (pin no.5) to the clock of cascaded ic.
