You can just tell me which comments or commands will be used and i need nothing else.
I and several other forum members tried to help you in this thread. I explained in detail what you needed to do, and gave pieces of code to help you. Then you said:
Will you please elaborate it I am not understanding the thing coz i am a newbie.
anyone here can please prepare a sketch (sample) for the said purpose?
You did not say specifically what you could not understand. This gave the impression that you had not attempted to understand anything. Then you asked for the code to be written for you.
Now you have started a new thread, asking for help with a more complicated circuit which now includes keypads and lcd screens.
If you could not understand how to use a single button to change a delay, how will you understand how to use a keypad and lcd to do the same?
Can you understand why we hesitate before we spend much of our time helping you?
You are trying to run before you have learned to walk. You must keep the project simple to begin with.
Show us how far you have got with the simple button controlling the traffic lights. Post your sketch and explain what it does today.
