Mode 10 Up Counter

This video shows the working of a 8 bit counter. The counter is of mode 10. in this ckt i use two sets of counters. The first counter for the display of lsb and the other for the msb. the 7 segment display only read up to 9 and go to 0 due to we used mode 10.
the first counter's clk pulse have an frequency of  1Hz sothe time will be 1sec(duty cycle must de 50), the other counters clk pulse is output of the first counter. using a logic  ckt when the four inputs are zero the second clk pulse is given. by that when the counter 1 read the digit 0 the counter 2 reads 1 and go on.

IC 7476,7400,7432,7447 & 7 segment display
