anyone can help me on how to light up 10 LEDs one after another sequentially?(after 10 pulse all will light up) which decoder should i use if IC 7490 decade counter is used?
 

You could clock a 1 into a serial in parallel out shift register.
 

how to connect the serial in parallel out shift register to the counter and decoder diagram? if i'm using 7490 and 7442 IC

Do you need to use those components?

What do you want your design to do?
