I’m trying to build a counter circuit capable of counting up to 5 digits, I really like this counter circuit on this website, my question can I modify this to county up 99999, and may I have the full circuit diagram if possible please.
Yes you can definitely count upto 99999, just make sure that the variable you are using to store or count this value should be atleast 32 bit. This becuase if you take a 16 bit interger varaible then it will onl sount upto 2^16 = 65535, which is less than 99999; but a 32 bit integer can handle upto 2^32 = 4294967296, which is faar greater than 99999.
