from this circuit the 7segment display start at 30 down to 0. and i want to make starting to 15 down to 0.
pls help me the deadline of this project is near.
I bet you have no circuit.... If you don't understand the circuit you have.. How can we help you... You have a binary counter there.. The 555 is just a clock... You need to work out what gates you need to change in order for the display to start at 15 not 30...
Someone will help you if you show us that you try it for yourself first..
Yelling will not help you at all. You don't need caps lock or so many exclamation points. They make it look like you're screaming at people, and I can assure you I will not respond if I see that sort of post.
