Hello poliguaco34

What, of all the things you require, you can do.

-I want to make a timer circuit using 555.
You know how to calculate everything to accomplish this ??

-Which count for a specific time 30 Sec. or 1 minute or 2 minutes and after this period it activates or triggers another circuit and I want to connect it to 7 Segments displays to see the time.
What is the ID number that you intend to use for the counter?
What is the identification number that you intend to use for the decoder?

-I want also to know how to make any digit counter (3 digit or 4 digit or any number).
This certainly You does not know how to do.

How much have you done ?

If you have a simulator for electronic circuits which you develop your projects, compressed, with WinZip or WinRar file generated with, and attach it here please.
