MOD 60 using 7490

In this video, MOD60 using 7490, I have explained how to make a MOD 60 counter using IC sn74ls90. It is a decade counter IC and output of this IC is in BCD code. MOD 60 is 0 to 59 counter circuit. This circuit is used to make digital clock in second hand and minutes hand.
Details of 7447 and 7448:
• SN74LS47 | SN74LS48 | ...

Sir how to make a down counter out of it?

[@bobkozlarekwa2sqq59]

I have a source which provides me once per second. I want to use your circuit to count the pulses so that I can create one pulse per minute. What additional circuitry do I need so that after 60th pulse “59”, it generates one pulse?

Can we use a switch instead of clock

[@EEWave]

Yes we can. Remember that pin 14 (clock input pin) is a active low pin so to use a switch, you must connect a pull up resistor with pin14. And as a clock signal, you should provide low signal (ground) to this.

Good afternoon sir, how to install push bottom with 555 ic? Or can we use other ic for push button?

[@itsnadchaos]

Is there any way to reset it while it is in this mode?

Sir, how to design mod-30 using 7490?

[@ahmedsheref7225]

I need to count to 5 in the frist counter
What i should to do ?

[@ahmeddiaa4142]

Zero doesn’t want to show up

[@charlesbabbage6786]

can you reset the count in between?? for Example if the count is at 21, can you add a switch to make the count 0?

[@EEWave]

Yes we can. I'll make a video on 7490 ic. There I'll explain.
