Clock with lcd and RTC

I have mad a clock with arduino and a lcd. I'm using a RTC to keep the time. Now i wat to make a alarm and a stopwatch and maybe even a timer. I have some codes that work. But i don't know how to connect them all to make a working system. And i also want to use a 4x4 keypad to set up the time and to switch from program. Can somebody help me?

Can somebody help me?

We will be able to help you, yes. But right now we can't. You need to read the forum sticky post. Until then, we can't help, not because we don't want to or refuse to, but because we don't have the information we need to help you.
