hi g,but I'm confused on what will I do. and I think my 7 segment display is broken :<<< it just gone crazy;<
Don't worry, we have all been there at some time.
Take a step back and use the two push buttons again and retest the 4026, when you have confirmed that is OK let me know.
Got you up to date photo....

Update:
This photo is not a bit of help, what is the purpose of the LED's etc..?
